I was getting the infamous click when you tried to start the vehicle. I knew that it had to do something with C2 because I would pull that off and reattach it and the Jeep would start like normal.
the secondary ground is going straight from the negative side of the battery to the engine ground. I figured that should of solved all the issues. Though I did cut about 3 inches off the O2 sensor wiring to be able to reroute it to the hood. So like you said there might of been a break close to the terminal lug that was removed during my rewiring of the ground.
i really appreciate the help I’ve been working on that off an on for that last month and with your help fixed it in two days. Really appreciate it!
