Alright, so i did this conversion in my truck. i had many questions in the wiring and buttons and what not.
basicly, i got a 1990 chevrolet sport, but came with manuel locks and windows, of course...
I took the harness out of a 1989 but couldnt find the releys, so with reserach and questions ask, weeks later, i found out...
1988-1994, does NOT have releys.
after that, i was wondering about the buttons, my buttons were shoot so was wondering about the ovall and square buttons, 1988-1990 (dont take my word on this, i think thats what it is) had squares ones and 1990-1994 had ovall ones. I think, 1990 and up might have had square ones i nthe lower end models. so you can take the outer shell of the ovall or square one and put the inner guts inside.
here are pictures for reffrence... hopfully helps someone out in the futur
