well in my previous picture i had said that those 3 wires go into the wiring harness, i was wrong about that now that i started putting my stuff in my shell. the white one goes into the blower motor and theres a little gray one the same size on the inside of the dash that should sit in the same place.

but now i have an issue with random plugs. i have two yellowish ones by the fuse box on the passenger side with no idea what goes there X( i havent put everything back in yet so hopefully ill find something to go there

The square plug on your eng harness that doesnt match the body one is the B1 plug (in tsrm).
89 cars used both styles, the 87-88 and the 89-90. Early 89 built before 1/89 is square and after is the other which is more rectangle.
You will need to de-pin one of the plugs and use the correct one. Make sure you use the pinout diagram and dont mix them up.

I recently did a 89 ge to gte and ended up using an 88 eng harness and repinned the plug because the 88 b1 plug had wires in different spots.

I might have the B1 plug if you need.
