Ok i finished redoing my harness using the info on lt1swap.com and everything came out great except i took out the engine coolant temp sensor signal out. Now im breaking my head trying to figure out how to put it back. The sensor has 2 wires 1 yellow and one gray i put the yellow one back to its pin but where does the grey one go too? Im freaking any help on this

Find a PCM pin diagram.

Check pin 80 in the same connector. I'll bet it's open right now.

Yeah i did take out pin 80 on the same connector i have the engine temp signal pin 74? So its that the pin for the grey wire?

So what Sensors are all needed for making a standalone harness? I just want to make sure im not missing anything double checking. And who can i send my pcm for reprogramming for vats etc.? Thanks for all the help

Sounds like its that pin..seems to be close to the car pinouts.

Need all your sensors on the engine except for emissions and the little bs like low oil.
