Report "Black main engine wiring connector block to the fuse box diagram for a 2006 Chevy Cobalt LS with 2.2 engine! I was replacing corroded connectors on the main engine wiring harness black block to the fuse box of my wifes car and did the the "stupidest" dumbest thing and let someone distract me and I placed some of the wires in the wrong places. The car will start but it runs rough. I have tried to find a wiring diagram or schematic for the wiring block but keep running into a brick wall. I have tried to move the wires around, and still get the same results. It's only 4 wires that are screwed up, however, those 4 wires are stopping the car from running right. Yes the car was running well except for a couple of relays getting a little hot. The black wiring block for our Cobalt is a 17 pin connector. I need some help. I'm hoping someone out there has a picture, diagram, schematic, or sujestion of a website that they can share"
