Can 2019 Jeep Wrangler Use Hardwired 4-Flat Wiring Harness

Question:

2019 WRANGLER JL Sport S has regular bulbs not LEDs. I only need the flat 4 for a small trailer that has LEDs - not much load, only 2 combo stop turn tail marker lights all in one. Will Item # HM48035 work?

Yes, you can use the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector # HM48035 on your 2019 Jeep Wrangler if you want to hardwire a 4-flat, though I do recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786 which fits your '19 Jeep and includes a power module connected to your battery. This is important because you won't overload your electrical system with this harness, something that will protect your Jeep in a way the Hopkins harness cannot.

If you go with the Hopkins harness you will need Quick Splices # SWC502905-1 when connecting your wires. I also highly recommend using Dielectric Grease for Electrical Connectors # 11755 to help prevent any type of corrosion in your connector; using it will increase your 4-way's durability and extend its lifespan.
