im currently doing a tbi swap but im not very far along yet. i got a fuel pump from summit thats made for tbi conversion. they also have a tbi conversion plate to adapt over your factory spreadbore to tbi so you dont have to change intakes. I ended up getting the entire harness out of the 89 that the rest of my parts come out of. as far as the 89 im going to have to convert the headlight switch, wiper motor , brake switch, cruise switch but luckily heat and ac will be easy since i have vintage air. the reason i didnt use a later harness is unless you use the proper trans it will set the check eng light. also it would seem that there isnt alot of info on the board for the tbi conversion and some of the questions that i have asked here went completely unanswered so i figure im pretty much on my own with my build, but anything i can help you with pm me and i will try. i think i have all my parts together and just started with the build so i will have more info soon.
