This shows the location of the 3 severed wires. They Y off the harness where the alternator pigtails are.

Here's a closeup of the three wires

Here is one of the pigtails I found down inside the engine bay. I have no clue at what point it popped off or where it came from. I think it may go to the intake manifold?

Here's two other things I found in the bay also. Pretty sure these aren't OEM since they're multicolored. But maybe that combined with the location of three severed wires might give someone an idea?

If anyone has a clue on what these might be or go to that'd be amazing. Even suggestions on things to check. Im curious if maybe one of them also goes to the oil pressure sender in the back of the block? No clue. It's kind of frustrating me and I'm trying to wrap up this engine swap... any help would be really appreciated.

 

yellow with green stripe and black go to cooling fan switch on the back of the block
yellow with red stripe goes to oil pressure switch on the back of the block

 

awesome, thank you much!

 

reference the last picture - those appear to be the wires for the back-up lights - go to the switch on top of the transmission (if it has manual transmission) - one yellow and one green with black stripe

 

thanks, any idea what those rectangular shaped pigtails go to? The ones not labeled on the diagram.

also this is not related to the original question but I'm plugging a d16z6 intake manifold into this harness. I had a female plug FITV on the old intake, can't seem to find that connection on the z6 intake.

 

not sure what rectangular shaped pigtails you are referring to

the Z6 doesn't have a FITV - just leave the plug not connected - won't hurt anything

 

after some googling and comparing my old to new intake I think that's the pigtail I was talking about. Thanks!
