Recommended Trailer Wiring Harness for 2015 Jeep Wrangler

Question

Question:

Hello, I have a 2015 Jeep Wrangle that I have wired to flat tow behind my RV. I also recently added a hitch to the jeep and would like to put a 4 pin connector for brakes and turn signals if I tow. Can I run both wiring kits? I hope this makes sense. I have purchased the flat towing kit and relay from etrailer if you can look it up and advise the best kit to add the trailer lighting connector. Thanks

It sounds like you just need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118416, which I recommend because of the reliability of Tekonsha wiring harnesses. Your trailer wiring will still be active even with the flat towing wiring receiving a signal, so there's nothing to worry about with this configuration.
