GTM wiring

[Alcarp]

My car has no donor, what wiring parts and computors do I need?

I ended up getting a harness built by Howell, and it came with the PCM for my engine.

My GTM was purchased used which already had a Painless Wiring kit partially installed. All the wires are labeled which makes routing, and connecting much easier.
This takes care of all the non-engine related components.

You may be fine with just the PCM unless you want options like remote locks, telescopic steering, active Lighting, HUD, etc.
