Expert Reply:

If you have a plug and play tow bar lighting harness that fits your 2018 Jeep JL Wrangler you would not need additional diodes and you'd be good to go as-is. Now if you have a plug and play trailer wiring harness you should note that these cannot be used in reverse as tow bar lighting so you would need to go with a lighting kit like the Roadmaster # RM-15267.
