So happy we got the wiring harness to go with the lights to make all the modes work! I love the different settings, the on/off and mode buttons the harness comes with is great, works well, looks nice installed. The harness is great quality, although for my 4 door Jeep we had to add about 6’ of wire onto the harness to make it reach to the rear bumper. Definitely recommend this for your multi- mode lights!

It’s easy plug and play but

Easily plug and play. Connectors were cheap but came with extras Incase they needed replaced. I installed on 2016 wrangler. But the switch is too short to have next to my driver side so I have yet to figure something out with that. It’s definitely a universal wiring harness that’s not throughly thought through.

Mode switch pigtail a little large for firewall pass through

Harness works great, quick and easy to install, only issue I had was the mode switch pigtail was a little large to push into firewall pass through and it could use an additional 2’ to 3’ of wire on mode switch end

Poor quality switches

Main power switch didn’t work and since I didn’t get a chance to install when I ordered it, I can’t return it! Once again Amazon gets my money.
