Tow Vehicle electrical

[dimples]

I just installed a 2nd vehicle Invisibrake kit in 03 Jeep Wrangler as well as a Diode Wiring kit and Brake Relay kit. All the electrical functions work in the car i.e. turn signals, brake lights, and running lights. However, when I hook up the motorhome (07' Diplomat) to the car the Inivsibrake works, brake lights work, and driver turn signal work. However, the passenger turn signal is exceptionally dim. I checked the front and rear grounds on the car and they are functioning. Does anyone have any suggestions as to where I should look to resolve the issue?

Thanks in advance for your help,
Dan

This is a known issue with Wranglers. I have a 2019. The MH is sending turn, stop, tail info and so is the braking system in the Jeep. I saw one solution from a wiring harness manufacturer that included a switch but that seemed like a bothersome solution. The only other way to address it that I know of is to buy the crazy expensive Mopar wiring harness, which is what I did. I'll try to find the details on this.
