Review: All the Wiring is here for a 4 Pin Connection - Everything is here for the Wiring. You do need to run this up into the Hood area and connect the Battery Terminals. There is a lot of length here, I was able to dress this across the front of the Hood and bring the cable down to the Frame and run a fish tape down my frame pull the wire inside the frame and up into the back lights to get everything connected. Took me about 2 hours from Start to Finish to get everything run, connected and dressed.
Review: Works great 2 years later - Worked perfect for my 2018 Jeep wrangler jlu.. 100% plug and play, super easy to install.. been on my Jeep for 2 years and it’s still going strong
