This 5.0 Resto 1987-1993 Mustang 5.0L manual transmission harness is a direct replacement for damaged, melted, or malfunctioning stock harnesses. It can also be used for an automatic to manual transmission swap for a clean, factory look. This harness connects the main vehicle harness to the transmission area and does not include the short harness at the transmission. Manufactured with factory correct connectors and terminals, quality crosslink automotive grade wire, and high temp covering. The harness includes connections for the speed sensor, reverse light switch, and neutral safety switch. This matches factory dimensions for easy, trouble-free installation!

Follow along as we go over the installation steps:

Install

  1. Disconnect the battery
  2. Raise the vehicle and secure it appropriately.
  3. To perform this installation it will be necessary to remove the driver’s side seat, carpet, and kick panel cover.
  4. Begin removing the existing transmission harness by disconnecting the harness from the main harness at the kick panel area and at the transmission. Note how the harness is routed. Carefully pull the grommet loose at the transmission tunnel and remove the harness.
  5. Install replacement harness following factory routing.
  6. Complete the installation by confirming the harness is routed away from the exhaust and any moving parts.

That's it! We at LMR hope this simple, but important installation procedure makes installing your 5.0 Resto Manual Transmission Harness a breeze!
