First of all, thank you for all of the help I have read from here. Y'all have helped me more times than you know. Now I have a question. I just had a spark plug blow out in my 07 expy. Bought the kit and repaired it. While I was repairing I realized I had this wire that was disconnected. Where the heck is it supposed to go? I can't find anything that looks like it should attach to. Passenger side, front of engine.
