Question:

On the towed vehicle 2018 F-150 4x4, Halogen lights Can I cut the four way flat plug off the BLU92HR, and wire it into a towed vehicle mounted 7-Blade outlet? The intention is to wire in the Towed Vehicle Charge Lineinch BLU44ER to the 7-Blade outlet, and use a single 7-blade cable from Coach to towed vehicle providing run/brake/turn and charge line. It seems like this should work? Am I missing something?

Hey Rick, thanks for reaching out. I see you already got your order placed but I wanted to make sure your question was answered.

Yes, you can cut the 4-way plug off the # BLU92HR and wire it to a 6-pin or 7-pin plug. People actually do this all the time for exactly the reason you stated. They want a plug-in lighting connection and want to also run a charge line. So, you were on the right track and not missing anything at all.

Hey Rick, how did the wiring go when you connected the Blue Ox tow bar kit to the 7-blade outlet on your F-150? Your setup sounds like a clean way to handle both lighting and the charge line. Sharing how it turned out could help others planning a similar setup.
