Question:
What parts do I need to install a Red arc tow pro elite on a 2018 Jeep Wrangler JL with the “half tow package” where the wiring harness goes to the battery with the blue service brake wire?

Hello Matt, thanks for reaching out. Does your 2018 Wrangler JL already have a 7-way trailer plug on the back. Not quite sure what the "half tow package" would include but if you don't already have a 7-way or 4-flat, you will need the Curt T-Connector # 56407 and the Universal Installation Kit # ETBC7 to complete your wiring.
Then for the brake controller, the Redarc # RED85CR is what you will need. This comes with all of the necessary wiring, mounting panel and pigtail for your Wrangler.

Hey Matt, did you have a chance to check if your Wrangler already has a 7-way trailer plug? I’d love to hear how the installation went, as it could help others with similar setups.
