Warren99 Posted December 31, 2022 Share Posted December 31, 2022 I'm swapping the interior from an 87 Chief(auto) into my 89 base(manual). For the interior wiring, I was planning on basically just gutting my truck, then just using all of the wiring from 87 starting at the fuse panel connector. Is there anything wrong or not plug and play about this? Also, I thought I remembered reading somewhere that an 89 engine computer is more advanced or better than an 87, so should I want to, or maybe even need to incorporate my current engine computer?
