Hey guys this might be a stupid thread but I can't find any information anywhere and I'm desperate. What is this connector that is part of my emissions harness alongside the primary injector wires and where does it plug into? Any help is greatly appreciated!

 

its for the aux fan if you have an automatic or a turbo, if you just have a manual NA, its taped to the harness

 

Single pin. Looks like o2 sensor to me..since it looks like it is near the OMP connectors , no?
