Question:
Hello, I flat tow a 2011 Jeep Wrangler behind a motorhome. I have a plug-and-play for the lights that goes to a 7-way to a 6-way to the jeep. I would like to use the 4-way plug on the jeep to power a light bar on a bike rack. Do you have any recommendations for this setup? Thank You

Hi Charles. Yes, you can absolutely use the 4 way plug on your 2011 Jeep Wrangler to power a light bar on a bike rack while flat towing. Since your Jeep is already receiving the lighting signals from the motorhome through the 7 way to 6 way harness, that 4 way connector on the Jeep will carry the same tail, turn, and brake signals.
Does your bike rack already have a built-in light bar? If not, the Curt Auxiliary LED Indicator Lights # C53201 are a great option that can be added to virtually any bike rack. They will plug right into the 4-way plug on your Jeep. This gives you a simple and reliable way to add visibility at the back of your bike rack while towing.
Also, please note if your 4-flat is factory, it likely will not be live when being towed. It has to be an aftermarket 4-flat like part # 118416.
Do you already have a bike rack you plan to use?
Let me know if there is anything else I can do to help!
