I have a loose connector right by the SPOUT it a 2 wire connector. I am smart enough to know it doesnt go way over on the other side of the truck. It was just down right above the oil filter.

Could it be from ur knock sensor under the intake

Irod I looked and that is not it. This is a big bundle of wires running between the distributor and engine block it then splits into 5 smaller bundles one bundle goes the throttle position sensor and the 3 other bundles go to the area of the block below the EGR . The last bundle just has the one connector with the red and black wire coming out of it. I watched about 1000 you tubes today and only one showed that connector and it was laying there like mine!!!

Ok I found another truck. Guy was kind enough to let me at his wiring. The connector that I have goes in the last plug on the block under the ERG VALVE. Problem is it must be for an option I don't have cause on my truck the is no plug there just a hole in a sheet metal flange where it would have went. Anybody know what it was for?
