    I would love to get an actual wiring diagram of the truck so I can see what wires are going to each door and what plug they come from so I can figure out what to hook up my new mirrors to.

    They are not what came on this year truck, but will bolt on.

*2 - On BASE model trucks the door trigger wires are in the LIGHT BLUE plug at BCM, pins B4 Drivers door and A5 Passengers door. On 4 door trucks the Left Rear door trigger wire is LIGHT BLUE/BLACK, pin A3, the Right Rear door is LIGHT GREEN/BLACK, pin A2. They are in the PURPLE plug at the BCM. Use all wires and diode isolate.

*4 - The PCM (Power Control Module) is in the left front of the engine compartment to the left of the fan shroud. The tach wire is in the GREEN plug, pin 10. For tach you can also go to any of the ignition coils and use the wire that is NOT PINK, BLACK or BROWN. Wait-to-Start wire is BLUE in instrument cluster or PCM.

I'm trying to install a Tekonsha trailer brakes and need the wiring diagram


The controller should have wiring diagrams with it. Also try http://www.etrailer.com/faq-wiring.aspx. The truck should have a harness that plugs into the factory harness under the dash. The harness paperwork will describe where it plugs into and what wires go where along with fuse location. If you don't hav the harness, you can get it from the dealer or the site listed above.

How do you install a driver side mirror?


hey, I replaced a mirror on a 2002 civic lx coupe.

1) Pry off the small pastic traingular piece from the interior of your door.
2) Disconnect the wiring to the mirror
3) There will be 3 bolts that attach the mirror to the car, remove these and the mirror can be removed. To put on the new mirror just do everything in reverse

Just make sure you order the right mirror, I accidentally order the mirror for the sedan model the first time and they are not interchangable.

Hope this helps
