My new JL Sahara has blind spot and cross traffic sonar with LED lights. I recently purchased a Roadmaster wiring harness for flat towing from Etrailer and took it to my local 4 wheel drive shop. They installed it. Now, my blind spot/cross traffic sonar indicators aren't working. I took it to the local dealer and they won't touch it because they say I modified the wiring harness. Any ideas about what's gone wrong?

There is no "flat tow harness" available for the JL as of date sold by eTrailer. Removal of the harness at the tail lights are in order to hopefully restore the "sonar". Good luck and keep us posted.

I didn’t want to dork with diodes when I wired my Honda CRV, so I bought a light kit from etrailer where I added separate bulbs into the tail light assembly. A bit more work on the install, but I liked the end result.

I don’t see a similar product for Jeeps, but I did find this. They are two magnetic lights that work off a transmitter that plugs into the tow vehicle. No working required.

Sweet. The wire is a pain. I bought the wired set for use on my current, soon to be previous, MINI toad. The Wind blown wire chaffed the paint in a few spots even though I tied them off. So I had the diodes done... now I’m selling it ... ha

Oh yea, learned the wires flapping in the wind lesson the hard way on my Murano’s paint job. Completely forgot about that
