Hi Bob - Thanks for the suggestion. I may end up having to do that, assuming I can find 1) a salvage yard, 2) a storage yard who will allow work 2B done, and/or 3) a good tech. 🙂 I don't mind providing the incentive ($$), just don't know how to locate a good wiring guy and new connector. May end up having to tackle it myself. If I can source a new connector, I probably will, just to move the project along. Of course, I'll probably have to have it towed again to somewhere I'm allowed to work on it. Probably should have just left it in my backyard and tackled it myself to begin with. Only reason I didn't is because I have a warranty that's supposed to cover these repairs. I assumed getting warranty to pay for it would a struggle, but never figured I'd be outdone by the repair shop! LOL

Hi Jim - Thanks for the feedback. The repair shop assures me that it is DEFINITELY the "Monaco side" wiring harness, not the Detroit Diesel side. That's why they are washing their hands of it (pass the buck, anyone?). I too think a good tech should be able to splice and re-wire the connector, but where do I get the new connector and the good tech? Hi Tim - Thanks. I may have to go do that myself. I asked the shop manager if he could get me a new connector (makes sense, since the ECU is a Detroit Diesel unit). He said he would check, but haven't heard back from him on it. I've seen a number of Detroit Diesel connector repair kits, but not sure which one might help.

Hi Ivan - Thanks for your help! Looks to me like the thing to do would be to re-wire that connector, but the Detroit Diesel shop refuses to even consider that and won't replace the ECU (again) until "somebody else" fixes the wiring. Locally, I have to pay $50/mile for towing so I am hesitant to have it towed somewhere else to fix the wiring then towed back to replace the ECU. Here's the pictures I took of the damage.

I know this thread is old, but I have this issue and the wiring harness is burned up. Per the above, the recommendation is to replace the wiring harness. Does anyone know where I can get one? New or used (in working condition)? Please let me know if you have any thoughts. Thanks. Eric

Hi All - I'm new to the forum, so please forgive me if I post this in the wrong place and be so kind as to move it for me. I am DESPERATELY in need of help. I didn't find out about the problem where coolant wicks down to the ECU and shorts it out until it happened to me the 2nd time. Last November, it happened and after nine weeks and $4688 it was back running again. Unfortunately, they didn't replace the broken coolant level sensor, so it's happened again! This time, it burned the wiring harness that goes to the coach (from the ECU) and the repair shop says they cannot find parts to fix it. They offer no suggestions. Does anyone know where I can get the wiring harness from the ECU to the coach (Monaco side, not the Detroit Diesel side of the ECU)? I am at my wit's end with the shop telling me "it can't be fixed". Thanks in advance for your help! Eric
