So the previous owner really hacked up the wiring and im trying to restore this thing to factory. Not sure if they did this because the coolant temp sensor went out and they decided to just bypass? There is a switch in place that is spliced in to the main harness and the Cold Start injector. Previous owner stated that if the car has been sitting for a while then I need to turn the switch on > start the engine > then turn the switch off. Or if the car is already warm then just keep the switch off and should work fine.

I really would like to have that cold start injector spliced back to the harness properly. Anyone know of which colors from the CSI go to the main harness? They spliced it close to the injector itself at the manifold.

Thanks!

 

Here's how the CSI system works:

Unfortunately, schematic is for 1988 22R-E. I don't know exactly how it's wired on your 3.0
