So I picked up this 2.3 auto '86 Foxbody coupe for $500.


I plan to install a TBI 350 with a cam and a few bolt-ons. I got this complete wiring harness (body and dash) out of a '99 5.7 Yukon Denali.




Now, I know 350/mustang swaps have been done 100 times, but usually with a carb. Can anybody point me in a direction for doing one with a TBI? Namly, which wires on the harness that are useless and needs to go. A few wires on the harness have been cut, but none of which went to the engine bay, so I'm hoping I won't need to add/fix any wiring. Also, will this harness work with any 350/5.7 TBI engines, or just certain years (i.e. I have a TBI 350 from a ~95 Chevy truck ready, just don't know if I'll need to swap any sensors, eta)
