87-95 TBI engines will be a direct drop in, with minor differences in sensors. Knock sensor values, TPS connector, and I believe the spark control changed around 1993, off the top of my head. But for the most part, those years will be drop in ready.

Awesome because I have a line on a 1990 k1500 motor for cheap.so I'll pretty much have to do is maybe wire in different sensors? Because that sounds a lot easier than what I was trying to do lol

If it's a 1990, I believe it will be a complete bolt in, plug and play. No need to change anything.
