I have recently added the necessary hardware to two my 2018 JL behind my RV. I'm using a Ready Brut Elite tow bar which I like.
The breaking process is integrated into the design which is activated when breaking which pulls a cable attached from the Ready Brut to the break pedal. It all works as designed but is not as efficient as when the Jeeps vacuum assist is working (normal operation when Jeep ignition is on).
Since it is not feasible to leave the ignition on while towing the Jeep, I began to look at other alternatives. It turns out that this model Jeep uses an electric vacuum assist pump rather than taking it from the intake manifold. As my engineering side kicked in, I thought that if I could energize that pump from the RV, when the RV is running, I could connect that +12vds to the pump through a cable, and get the results I was looking for.
All that said, has anyone else out there done this and, if so, would you be willing to share your experiences and knowledge to success?
It seems to be pretty simple with the sticking points being finding the male and female plugs for the pump and where it connects to the wiring harness. The reason for that is that a diode needs to be added to the circuit such that when the RV is suppling +12vdc to the pump, you want to keep that voltage from going back into the circuitry of the Jeep. Hope that makes sense. Making a jumper assembly with the diode, wires to the RV, and connectors would make installation simple and reversible.
Appreciate your feedback.
