Question:

I have a 2004 Jayco class C motorhome on the E450 chassis and I need to buy a trailer brake controller for it along with the harness adapter for it, 4 to 7 rear trailer plug and some wire that goes from the rear factory plug to the trailer connector.

Hi Manny; are you saying you have a factory 4-way on your Jayco right now? If that is correct, you can upgrade it to a 7-way using the # ETBC7. This comes with the adapter, wiring, and everything else you need for installation.

For a brake controller I recommend the Redarc Tow-Pro Liberty. It is simple, reliable, and doesn't take up space in the cab. If you have the factory brake controller port you will need to tie in the brake output wire from the 7-way and then you can use the # RED96CR with the custom wiring harness. If you do not have the brake controller port, you can use the # RED52VR with the universal wiring harness.

What are you towing with the Jayco?
