Question:

I want to flat tow my 2021 Ford F-150 4x4 behind my motorhome. I already have parts picked out so I think I'm good there, but is there a no-cut plug and play flat tow wiring harness available?

Expert Reply:

Although we have wiring harness options that will work for your truck, the Hopkins # HM56009 taillight harness for towed vehicles wouldn't work for your 2021 Ford F-150, it only fits up through the 2020 model year.

I'd recommend using a diode kit like part # RM-15267, that would install as shown in the video I've linked for you. You'll also want to use a # RM-156-25 charge line kit to keep the truck's battery topped off while you're towing the vehicle. I've also linked to an install video for the charge line kit.
