Question:

I am needing a wiring harness that also features the 7 pin plug, not just the blade style connector. I must have the 7 pin to pull my bass boat. Our 2021 Jeep Wrangler Unlimited did not come with the factory tow package. I have added a Hitch, just need wiring harness.

To get the wiring configuration you're wanting you'll need to install the T-One Vehicle Wiring Harness # 118786 on your 2021 Jeep Wrangler Unlimited. This gives you a 4-Way with the standard trailer light circuits.

Then from here we need to install the Universal Wiring Kit # ETBC7. This comes with all of the wiring and parts to get you a fully-functional 7-Way but the nice thing about this wiring kit is it also retains the 4-Way part as well so you don't need an adapter for that.

From here is sounds like your bass boat trailer has a 7-Pin connection with round pins instead of the blades so for this you need the Adapter # PK12727 which plugs into the 7-Way blade and gives you a 7-Pin round pin connection.

Attached are some videos for you to check out.
