Re: My swap. 5.3 into a 1990 3/4 ton 4x4 Suburban.
One more question for ya. What did you do for the "in gear" wire to tell you pcm to idle down when you put it in gear. I know on the newer trucks the safety switch and "in gear" switch are the same switch. But on my '85, all i can find is the reverse light switch at the bottom of my column. I know i have a safety switch cause i could never start it in any other gear when i had the 350 in it, but i can't find it.
