Does Wiring Harness on 2018 Jeep Wrangler Need Hot Lead to Battery?
Question:
I noted that there is a 12V cigarette lighter adapter charging port on the driver side of the Jeep just 18 inches from the tail light assemble. This port is hot all the time. Why not tap the positive on this port rather than run a wire the full length of the Jeep to the battery?? What is the amperage need of the control module. I am assuming that the charging port is good for at least 15 amps and would make for a much easier and safer install? Thanks

The T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56407 that fits your 2018 Jeep Wrangler MUST have a hot lead run to the battery because the port you are referencing is not rated to handle additional amperage. Using this instead of a battery can lead to a fire or fried electrical circuits in your vehicle, so please run the hot lead to your Jeep's battery.
