I installed a cooltech harness on my 2007 JK and I am having a pretty major issue I can't seem to get resolved with cooltech customer service.
After following the install directions carefully, ensuring each prong on jeep plug matched function/power signal coming from MH (using cooltech supplied umbilical), and with the jeep battery disconnected, the dash lights up and relays click when I connect jeep to MH. I have inspected all plugs inspected for any damage to wire shielding and all is good. I did notice however that all prongs on jeep plug have connectivity to ground, both with the battery connected and disconnected, should this be the case? Also the running lights on the jeep appear to be dimmer when powered by MH vs powered by jeep battery. The only solution that works is to pull the IOD fuse along with several other relays until no more clicking.
MH is a 2005 southwind, and I have also attached install intructions and pic of my jeep plug config to match MH output
