What a can o worms!
There's some good pics here from Merv who continues to be a great supporter of this forum
, be mindful of the diagrams though as my engine is a '93 mustang and quite a few of the wiring colours and component descriptions are different in my car to the published ones. As yours is a a post '00 engine heaven knows how different it will be
I'm pretty much finished wiring mine myself and readying it for the trimmer. I powered it up a few days ago and had headlights coming on instead of parkers and the immobiliser going crazy. It did turn over though and the fuel pump jumped into life.
I've been booked in to the trimmer for 6 months and don't want to reschedule him so haven't time to sort out the bugs before i go away for 5 weeks on Monday. So like you I can look forward to many hours of more electrical fun soon
As Merv said on another post, you'll get to know every wire in the car.
Good luck
Greg
