First one is your O2 sensor. Did this harness come from a truck with an Auto harness? That last one I believe is for one of the idle up plugs. Coolant temp sensor connector is green. CSTTS is black and the one for you temp gauge is yellowish.

How would I know if it were an auto harness? Because from what I know this truck has always been manual 22re the engine is just rebuilt

The first white one that is square, is that for the 4wd light or reverse lights? The connector will be on your tranny.

Yes thank you I found them all there was one on the tranny, transfer case, and one was the connections to the rear wiring harness. Thank you for the help this has been stumping me for a while.

Okay I lied to myself I though I had found all of them but I still have 1 left to find. It's the first picture and I can't find where it goes. I assumed it connected to the rear wiring harness for brake and reverse lights but that actually goes up by the brain. Does anyone have any idea where it might go? Am I missing something?

Check your oxygen sensor, it should be close or behind your transfer case.
