Carb to TBI wiring harness Trouble.

[Liquidsteel2]

I wrecked my RS 1990 Camaro, which had a 305 TBI in, I took the engine out and put it in a 1984 Camaro, I took the wiring harness from the 1990 and trying to switch it over to the 84, Do i have to switch the fuse box and the wires behind the dashboard, over to the 84 to make this work. Or is there a simpilar way?

I've already switched the gas tanks out, with the 1 90 rs, into the 84. Not sure where to find the wiring diagram for the RS or 84, tried autoparts place, but they claim they don't have em...

all you should need is the engine wireing harness and the ecm, are you using the 84 tranny or the 90?
