GEN 3 Tacoma Auto Start


Full disclosure N2 Designs is having me write a new install guide for this kit so if these end up being very similar to his included instructions in the future you will know why. This is not however what I sent him. Similar but that was much more professional. This is just a quick write up.

Remove lower steering column cover.

Remove driver side Door Entry Panel.

  1. The Door Entry Panel is the bottom plastic cover between the driver seat and the door.
  2. This is clipped in. Pull straight up or use trim tools to pop clips loose. Work rear to front until panel is free. Set aside.

Remove driver side Kick Panel.

  1. On the firewall there is one plastic clip. To remove this clip use 10mm socket. It should come loose with a half turn.
  2. Using trim tools if available pull the kick panel towards the rear and center of the vehicle. Two white angled clips hold the panel in. Ensure the clips are with the panel. This will ensure easier installation when finished. Set panel aside.

Remove lower driver side dashboard trim.

  1. Remove 10mm bolt at lower left corner of panel. This bolt was exposed by removing the kick panel.
  2. Remove two 10mm/Philips screws from lower edge of dashboard trim.
  3. The panel is held in by clips. Start at the bottom edge of the panel and using trim tool work around the edge until all clips are loose.
  4. At this point the panel will be loose but there are still several electrical connectors holding it. It is not necessary to remove these connections. Allow the panel to hang.

Install N2 Designs Wiring Harness.

  1. The provided wiring harness allows for add on modules (Cellphone Integration available separately) and is also compatible with other vehicles. This harness has several connectors that WILL NOT be used for this installation.
  2. Locate the BLACK connector on the bottom right of the steering column and disconnect it.
  3. Route the supplied harness with the two black connectors behind the dash and up to the connector. Connect the factory wiring connector to the harness and then plug the harness into the steering column. Route the wire harness with the other wires in the area. SHOWN WITH HARNESS INSTALLED
