Attached are pics of my failed 7 pole connector. The part number is (Hopkins #XXX). I took the RV to 24/7 Motorcoach and Victoria, Parts Manager, [XXX] Ext #5) filed claim #XXX on XXX. The claim was "Under Review" for almost a month. Now shows Approved Processing. I have a trip planned for tomorrow with my enclosed car trailer and did not have time to wait for the part. I purchased the replacement part myself from NAPA Auto Parts (Part #755-2621) and installed it myself. The same failure occurred. One of the pins pulled out and the lights/turn signals/brake/hazard/running lights/brake controller did not function properly or at all. I took the RV back to 24/7 Motorcoach and they removed the entire old back part of the connector which was connected directly to the 7 wires with spades, heat shrink tubing and silicone. They replaced the part with a different part (Hopkins #48474) which does not require a wiring harness. My Dynamax DX3 32KD did not come with a wiring harness. The original part #XXXrequires a harness to be installed properly and Hopkins sells an optional harness (part #40985) which MUST BE USED with part #40950. That is why the pin kept pulling out and the other pins were disconnected from the connector. In addition, the 20amp fuse in the engine compartment that provides power to the connector was blown. I have the blown fuse. I also have all of the part from the failed connector and all of the heat shrink and silicone pieces along with the failed connector. Clearly, Dynamax installed the connector incorrectly and this caused the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
