[QUOTE="Massie02GT, post: 16393182, member: 116991"] Well it’s that time. Within the next few days my “new” 04 Cobra motor will be delivered, and I’m trying to plan out the swap in my head. To those of you that have done this swap: what wiring did you use? The motor is coming with the engine harness, but no ECU. Can the engine harness plug into my GT ECU and function properly? If not - what steps have to be taken to use the GT wiring to make the 4v work? I know I’ve read that polarity must be swapped, I just can’t remember if it’s the COP or the injectors, or both. Also I know I’ll have to extend some wiring, so which gauge wire should I use for that? Overall I expect this swap to be pretty straightforward, but who knows. It’ll be my first motor swap experience. Thankfully I’m on no real timeline. [/QUOTE]
