Need Replacement Wiring Harness/Connectors For Ground Control Landing Gear  

Updated 11/03/2025 | Published 12/30/2024

Question:

I have a Grand Design Reflection 5th wheel. I had a blow out on the passenger side rear wheel and it tore the wires up on the rear jack. My question is, do you have to buy thw whole harness or do you have the ends to splice the existing wires? See attached photos.

Hey Kenny, thanks for reaching out, and sorry to hear about your blow out. The best solution here will be to buy a whole new harness part # LC307490. The ends of the connectors are not available separately, so a new harness will be the only way to get them. The # LC307490 mentioned above is intended for the front drivers-side, but if all you need is the connectors you could technically use it for the rear passenger side also.

Hey Kenny, how did things go with the replacement harness for your rear jack wiring? Your update could make it easier for the next person dealing with a similar repair.
