Electrical Drawing for Fuse M33 (Wrangler JK 2007)
Hi Everyone,
Hopefully, someone can help me.
My girlfriend was driving my jeep along the freeway when she started to experience a death wobble so she pulled over to the side of the freeway to stop the vehicle but when she went to restart the jeep, the jeep wouldn't start. We had the jeep towed home and when I looked at what the problem was, I found that the Fuse M33 (NGC-GPEC) had blown. I replaced the fuse and the jeep turned over a couple of times and when it finally started, the fuse blew again. I replaced the fuse a second time, the exact same thing happened.
My theory is when my girlfriend experienced the death wobble, a wire has moved and the insulation has melted and caused a short but unfortunately, I need some help understanding what wires are connected to fuse M33 (Next Generation Controller and Global Powertrain Engine Controller.).
Can someone please assist me in providing an electrical diagram that shows the wiring for fuse M33?
Thanks in advance.

I believe I had M32 issue with my 08. The windshield wiper fluid would continually spray as soon as I put the new fuse in. The TIPM module needed to be replaced in order to correct the issue. Not happy about it since at the time it was a dealer only. I know that's not the wiring diagram you were looking for, but keep the TIPM on your radar if you are tracing and testing the wires with zero results.

Hi, I have proven that the TIPM is OK and I can confirm that the fuse to the Powertrain Module only blows once the Jeep is running. I remove the spark plug leads to prevent the jeep from running and tried to start the Jeep several times and the fuse didn't blow. However, once the Jeep was running did the fuse blow.Does anyone have any information on what has activated from the Powertrain Module once a jeep is running?

If I can remember when I get on my laptop Saturday I will scout through 100 pages of wiring and send you what comes out of that fuse. Why did the death wobble arrive? Been there before or new?
