 Troubleshooting / Frequently Asked Questions

What does a neutral safety switch do, or how does the neutral safety switch function?

  • The safety switch senses when the clutch pedal is depressed to allow the Mustang to be started. It does this by completing the circuit allowing the starter to get a signal to start. If this switch goes back, the starter will not be a starting signal to turn over. 

What are the symptoms of a faulty neutral safety switch?

  • If your Mustang is not starting, your neutral safety switch may be the culprit. If you turn the key to your car and your starter is not getting a signal, you will need to work your way from the clutch safety switch to the starter solenoid and then the starter. This will allow you to find out what item is not working correctly. 

My Mustang will not start. Is it the clutch safety switch?

  • If your Mustang is turning over and not starting, the clutch safety switch will not be the culprit. If your Mustang does not turn over, it may be the clutch safety switch. If your Mustang is not turning over, you will want to check the battery, starter solenoid, starter/battery cables, and starter.

Ensure your Mustang starts every time with this 1986-2004 Mustang clutch pedal safety switch! This switch prevents your engine from starting unless the clutch pedal is fully pressed down. Once the pedal is engaged, the switch allows power to run through the ignition to the starter relay and then to the starter solenoid to start the engine. If the switch goes bad, you'll be stuck in a no-start condition. This high quality switch features the factory connections for a quick and easy installation. The switch installs next to your clutch pedal in the same manner as the factory switch did.

How’s it going everyone? Landan with Late Model Restoration. This video will cover my quick review and install on this clutch pedal safety switch intended for the 1986 to 2004 manual equipped Mustang.

If you’ve pressed the clutch in, turned the key over and your Mustang still doesn’t start; then you’re probably a candidate for a clutch pedal safety switch. This little guy is located on the clutch pedal assembly and plays an important role in vehicle safety. It prevents the engine from turning over unless the clutch pedal is fully depressed.

This safety switch features high quality, OE-grade construction, and is a direct replacement for all 1986 to 2004 manual equipped Mustangs. Now, if you any of you have swapped or plan on swapping to a manual transmission, then this safety switch is highly recommended to complete your swap.

It is very easy install, although the area you’re working in is fairly tight. I always remove my seat when working on anything under the dash. I mean in all reality, pulling a seat takes no time at all.

For this install, we are actually going to show you how this works outside of the vehicle. Simply disconnect the electrical connections, then remove and discard the old switch if equipped. This is done by removing the retaining nut and cotter pin.

Position the new switch into place and reinstall the retaining hardware. Plug in the electrical connection, give everything a solid once over, and you’re all finished.

This one is really easy guys other than the fact you’re working in a tight area. Regardless, this should take you no more than thirty minutes from start to finish.
