This 25-foot wiring harness connects your Dometic HRC or DDC rooftop air conditioning unit to its single wall-mounted control panel. If your AC remote won't communicate with the unit or you're installing a new system, this harness is the critical link that carries power and control signals between components.

Frequently Asked Questions
Q: Will this harness work with my Dometic rooftop AC if I'm replacing an old one?
A: Yes, as long as your unit is an HRC or DDC series model. This harness connects the rooftop unit to a single wall control panel. Verify your model number on the AC shroud before ordering.
Q: Can I extend this 25-foot harness if my RV layout needs more distance?
A: We don't recommend extending it yourself, as improper splicing can cause voltage drop and control signal loss. If you need a longer harness, contact our support team — we may have alternative lengths available.
Q: What's the difference between this single-control harness and a dual-control version?
A: This harness supports one wall-mounted thermostat. A dual-control harness would allow you to operate two separate zones independently. Choose based on your RV's climate control needs.
