or those who've never done it beyond wiring lights.
I'm swapping a 2003 4.3 Vortec and 4l60e into my 86 XJ, at least in theory. I'm dealing with the fact that I'm going to need either a Howell or Painless harness and a reflashed 'puter in order to make this work (the stock 4.3 harness is montrous).
Where I need some real tech help is understanding how the drivetrain (underhood) wiring interacts with the internal wiring (instruments, lights, AC, stereo, etc.).
Since the old drivetrain is gone, I can simply remove all the original underhood wiring, correct? Where do I do so? Where it terminates through the firewall?
And is it easier to do away with some or all of the internal wiring and dash as well? How do I know what goes and what stays? I could just build a flat dash and put in new guages, would that be simpler to wire?
The rig has a rat's nest behind the dash and it's pretty confusing. Any help or links to more info would be much appreciated.
