I know this is a commen problem but my freind has a 90' Rs, that came with a 305TBI, he bought 89 350TPI. well after the fact I found out that there is a big difference between the 89 and 90' C100 and C207 connectors. ive got the pinnouts for both years. i see that there many wires that are diff. Ive tried to pinn the 89 harness to match the 90 connectors, but there's just too much different. is it even possible to do this and the car run?

would it be better to get a 90' harness and convert to map setup?

is there an eazier solution?

thanks for any help.
