i got a 88 mpfi 2.8 car and a 87 iroc-z. i know its easier to buy a new tpi car but i wrecked mine. the motor is fine and it runs really strong. i got a really good deal on the 88 i paid 200 for it and thought that i cant find a better deal. the body is perfect besides a little surface rust on the drivers door and its only the size of a half dollar. well anyhow i got all the parts to do the switch as u can tell. the only thing i am worried about is the harness. can i plug the tpi harness into the harness for the body lights which goes into the fuse box. would it be easier just to buy a painless harness or switch my fuse block and inside harness. i already got the 2.8 motor out and the harness. im not in a really hurry to get it done i want to do it right. with the insurance money i bought a 79 chevy truck with a short bed and its sitting on a 4 inch suspion lift and a 2 inch body lift with 35 under that so i can run over camaros now. do u goes have any hints on anything i should to make the swap any easier thanks for the advice ahead of time. have a great day
