So I just finished reinstalling the new motor in my car. As I was looking things over I noticed 2 wires with bare ends. They are coming out of the harness right by the 5 & 7 injector connectors and appear to be light green and brown. I couldn't find any connectors that might have accidentally been pulled off and I haven't started plugging things in yet. Anyone have any insight as to what they might connect to? Here's a crappy cell phone pic to hopefully help.

 

Damn, this was supposed to be in the LT1 forum. I must have fat-fingered my phone and accidentally picked the wrong one.

 

No problemo. Moved.

 

Probably the EGR valve. That's the only thing that comes out of the harness at that location.

 

take a look at this and see if you can identify it, courtesy of shoebox

It looks like you are correct, and the harness picture seems to confirm it. Thanks for the quick responses guys.

 

Grey and brown are the wires to the EGR solenoid. Perhaps you are color blind (the one wire in the pic looks grey to me).

 

It was a bit hard to tell under the layer of grime coating everything
When I can drive this thing home from my roommate's shop it's going to get a few hours of attention with a spray bottle of Simple Green and a toothbrush.

 

haha I have a few of these cut wires hanging around on mine.. I don't throw codes so I know its egr related (that was tuned out)

 

I can't get away with that here. They do a visual inspection, including sticking mirrors under the car looking for cats, check for codes, then you've gotta pass the sniffer test. Not gonna stop me from adding LTs later, just gonna need the emissions set with a cat in the y-pipe.
