S197 Mustang Trunk Release Kit Installation (2005-09) - S197 Mustang Trunk Release Kit Installation (2005-09)

Like just about every new owner of a 2005-09 Mustang, I went hunting for the trunk button in the car only to find that Ford failed to put one in the car in the first place. Sure the button is on the keyfob, but what if it turns up missing or you don’t have it with you? Luckily, I wasn't the only one who felt this way and there is now a quick and easy solution for us!

LMR offers a 05-09 Mustang trunk release that requires no cutting or modifying and takes roughly 15 minutes to install. Out of the box, you will find the button already attached to its bezel with the wiring ready to go, as well as some zip ties and wire taps for installation.

Tools Required

  • Flat head screwdriver
  • Phillips screwdriver

Wiring in Center Console

  1. Turn the car off and remove the key. Remove any items that may be in your center console, cup holder, or passenger side floor.
  2. First we will be removing the center console cover. The cover is held on by two Phillips screws located in the rear of the console (towards the back of the car). Remove these screws and set them aside for re-installation later.

  4. Pull your emergency brake up as far as reasonably possible in order to make it easier to remove the center console panel. Note: the rubber boots that shroud the emergency brake lever tend to hug the lever as you attempt to remove the center console.
  5. Remove the leather bezel from the shifter (manual transmission) or trim bezel (automatic transmission). Note: On manual transmissions, you must unscrew the shifter ball in order to remove the leather bezel completely. While unscrewing the shifter ball, hold the leather boot in place so it does not get twisted up.

  7. Begin to carefully lift up on the entire center console cover. Several clips hold the console into place and they will un-snap as you pull up on the panel. You’ll want to keep the entire console cover level until all the clips un-snap, and then you can manipulate the panel as necessary to remove it. Generally, you will not need to pry upon any part of the console – it should un-snap from the base relatively easily.
  8. As you lift up on the console, you will need to carefully maneuver it over the emergency brake lever. If you are concerned about scratching the dash with the console, use a rag and drape it over the console end to act as a cushion.

  10. After the center console cover has been removed, gently set it off to the side for re-installation later.
  11. Remove the emergency brake access cover with a small plastic pry tool or flat head screwdriver (wrapped in a microfiber towel).
  12. S197 Mustang Trunk Release Kit Installation (2005-09) - S197 Mustang Trunk Release Kit Installation (2005-09)

  13. Install the included emergency brake access cover (with button) into the center console compartment. Wires come already connected to the switch. Route the wires through the hole vacated by the access cover you just removed.
  14. Locate the green and black wire running under the cup holder area towards the center console compartment. These wires plug into the 12-volt power supply located in your center console compartment. Using the supplied blue wire tap, slide the black wire onto the wire tap. The wire should sit in the middle of the two teeth. Squeeze down on the wire tap making sure it snaps closed. Do Not Cut The Wire! Note: If necessary, you can use a pair of pliers to squeeze the wire tap closed.

Routing wiring in passenger compartment

  1. At this point, use one or two of the supplied zip ties to safely secure the red and black wire away from the emergency brake assembly. We want to make sure that they are tied down so that we do not interfere with the e-brake operation. One option is to zip tie the switch wiring to the green/ black wires running to the 12-volt power supply.
  2. Route the red wire down the passenger side of the center console until you reach the shifter.
  3. Remove the trim panel located to the right of the radio controls. Gently pull the panel straight out.
  4. S197 Mustang Trunk Release Kit Installation (2005-09) - S197 Mustang Trunk Release Kit Installation (2005-09)

  5. Route the red wire towards the glove box. Now carefully re-install the trim panel you just removed. This will help hold the red wire in place. The panel re-installs the same way it was removed.

  7. Route the wire across the back of the glove compartment (there is a bracket which you can secure it to with zip ties). Check to make sure the wire will not interfere with glove box operation.
  8. At this point open the passenger side door (if not already open). The skid plate that says ‘Mustang’ (or ‘SVT’ if you have a GT500) will need to be pulled up slightly so that we can pull back the carpet. You can remove this panel if you would like, but it is not necessary or recommended as it is held on with double-sided tape on the outermost side (some model years are not taped down).
  9. Pull the end of the skid plate closest to the front of the car up slightly. You will hear it unsnap. Note: Be careful, this panel has sharp edges that can cut you.
  10. Now pull the carpeting back slightly to reveal a bundle of wire. Gently pull back some of the electrical tape to reveal all the wires.

  12. At this point it is important to note a few things – sometimes wire colors bleed onto each other over the years and it becomes tougher to differentiate between colors. You may also have a tough time seeing the colors because the wires are very small. Lastly, keep in mind that depending on the features your particular car has, it is possible to have more than one of the same color wire. When this happens you will always be tapping into the smaller of the two wires (the skinny 22 gauge wire).
  13. Using the supplied red wire tap, slide the thin white wire with pink stripe onto the wire tap. The wire should sit in the middle of the two teeth. Squeeze down on the wire tap making sure it snaps closed. Do not cut Wire! Note: the pink stripe on this wire may appear to be red or violet. With the 2007 Model years, Ford varied the color of the wire they used. If you find that the white wire with the pink stripe does not exist or does not work, you will most likely need to use the thin orange wire with pink stripe. In the event that the first wire didn’t work, place a piece of electrical tape over the area that you tapped into.
  14. Finish routing the red wire down to the skid plate and plug it into the red wire tap. Tuck it in behind the kick panel so that it is out of view.

Final Installation

  1. Double check everything to make sure it was connected properly. Test the switch to make sure the trunk opens when pressed. If it does not, visit the trouble shooting section below. Otherwise, proceed to the next step.
  2. Replace the carpet and then press down on the skid plate to snap back into place.
  3. Re-install center console cover the same way you removed it - be sure not to bump the dash.
  4. Replace the two screws that were removed from the center console cover during installation.
  5. Replace the bezel surrounding the transmission shifter. If equipped with a manual transmission, re-install the shifter boot/ knob.
  6. Enjoy your trunk release kit! The kit will operate the trunk release anytime, regardless of if the key is in the ignition or not. Be careful not to press it while driving or the trunk will open.

Trouble Shooting Guide

Trunk does not open when button is pressed

  • Check both wire taps that you installed earlier in installation – make sure both are closed completely.
  • Make sure you have used the red wire tap on the correct wire – sometimes the small wires make it difficult to determine wire color. As mentioned above, colors can bleed onto other wires over time. Use a magnifying glass to determine the wire color if necessary.

Cannot find the correct color wire on a 2007/08 model year

  • In rare instances, Ford varied the wire colors on some 2007/08 model years. Unfortunately, it is not possible to tell if your vehicle is affected until the beginning of the installation. If you believe you have a vehicle with this issue and have already tried locating a wire matching the color pattern(s) listed on page 3, the only other way to identify the proper wire is to locate the wire as it comes out of the SJB (Smart Junction Box). To do so, follow these instructions:
    1. Remove the negative cable on the battery to disconnect the vehicle's power.
    2. Un-bolt the SJB so that you can gain access to the connectors located behind it – it is located behind the passenger side kick panel.
    3. Locate the C2280C connector (it is labeled with part number C2280C).
    4. On the connector, locate pin#21 – this is the wire color that we are looking for and the one that will need to be tapped into with the red wire tap.

How’s it going everybody? Landan with Late Model Restoration. This video will cover my quick overview and install on this trunk release button kit from Starkey Products fitting all 2005 to 2009 Mustang.

If you own a 2005 to 2009 Mustang then you are more than likely familiar with the frustration of not having a trunk release button inside of the car. Ford remembered to put it on the key fob, but somehow throughout the 2005 to 2009 model years they totally forgot to put a button inside of the car. Beats me!

If you’re wanting to add the convenience of a trunk release button inside the car, then you should definitely consider this kit from Starkey Products. It features a seamless integration into the center console for easy access and factory-like fit and finish. The face-place is textured plastic to mimic the factory inner-console trim and also has an easy identifiable red push button that triggers the trunk release mechanism.

There is no drilling or cutting required, and installation can be done in no time at all. You will need a little bit of knowledge pertaining to electrical systems especially if you own a 2007 or early 2008 model Mustang.

In rare instances, Ford altered the wire colors for some 2007 and early 08 models. Unfortunately, this is something you won’t know until you begin the install. The good news though, it’s very easy to determine the correct wire and color that needs to be spliced with supplied Scotch locks.

To begin, disconnect the negative battery cable.

Inside the car, open the center console and locate the two rear Phillips head screws.

Remove these screws and set them aside.

Pull the emergency brake handle up as far as reasonably possible in order to have enough clearance to remove the center console panel.

If you own a manual Mustang, unscrew and remove the shift knob.
Now, pry up on the bezel if you have an automatic car or the shift boot if you have a manual car, and then set these components aside.

Carefully lift up on the console to release all of the clips holding it down.

Then manipulate the console out of the car and set it aside.

Inside of the center console remove the emergency brake access cover with a small plastic pry tool or a screwdriver wrapped in a microfiber towel.

Take the provided cover with push button and route the wires through the hole.

Then snap the cover into place.

Locate the green with black stripe wire running under the cup holder area.

This wire plugs into the 12 volt power supply located in the center console.

Using the supplied blue Scotch lock, slide the black wire into the Scotch lock.

This should sit in the middle of the two teeth.

Carefully squeeze down on the wire tap and make sure it snaps closed.

If necessary, use a pair of pliers to squeeze the Scotch lock closed.

Plug the black wire from the button wiring into the back of the blue Scotch lock.

Use one of the provided zip-ties to secure the wiring away from the emergency brake assembly.
Route the red wire down the passenger side of the center console until you reach the shifter.

Remove the trim panel to the right of the radio.

To do this, gently pull the panel straight out.

Now route the red wire toward the glove box.

You can go ahead and reinstall the trim piece you just removed.

Finish routing the red wire across the back of the glove box.

Go ahead and carefully pry up on the scuff plate so you can pull back the carpet.

Locate the bundle of wires and trim back some of the electrical tape.

Before continuing, I want to make note of a few things.

Overtime, colors can bleed together making the wires hard to differentiate from each other.

Also, depending on the features of your car, there may be two wires of the same color.

If this happens, make a mental note to yourself that you will always be tapping into the smaller of the two wires which is usually 22 gauge.

Using the supplied red Scotch lock, slide the thin white wire with pink stripe into the Scotch lock.

Squeeze down on the Scotch lock making sure it snaps closed.

A pair of pliers may be needed to do this.

Like I stated previously, Ford varied the wire color on 2007 and early 08 models.

If the white with pink stripe wire is not there, try and locate the orange wire with pink stripe.

If that color combination is not there either, a few extra steps are needed.

Remove the passenger side kick panel and then unbolt the Smart Junction Box.

Locate the C2280C connector.

On this connector, locate pin number 21.

Disconnect the C2280C connector from the Smart Junction Box and de-pin the harness.

Locate pin 21. In our case, it's an off-white wire with pink stripe.

This is the wire color that is needed for 2007 and early 08 models that do not have the white with pink stripe or orange with pink stripe wires.

Use the provided Scotch-Lock to tap the correct wire from pin 21.

Then plug in the red wire from the trunk release button.

Now you can finish routing the red wire down the scuff plate and plug it into the Scotch lock.

Reconnect the negative battery cable and test for operation.

Once that is complete, make sure and position the red wire away from the glove box assembly.

Position the red wire behind the kick panel so it is out of view.

Take this time to zip-tie the red wire out of the way and secure any remaining wire together.

Use a few more zip-ties for the wires in the middle console and near the emergency assembly.

Reassemble your interior components in reverse order.

Double check your work and you’re all finished.

For the most part guys, this is very straightforward, but can require a few extra steps if you have a 2007 or early 2008 model Mustang. All in all, set aside about an hour of your time to get this knocked out. Regardless, this trunk release kit is the perfect addition to every 2005 to 2009 S197 Mustang.
