How Does Towed Vehicle Battery Charge Kit part # DM66VR Attach to Ford Maverick Battery Terminal  

Updated 06/30/2025 | Published 08/08/2023

Question:

How best do you connect the Demco SBS towed vehicle battery charge wire to the Ford Maverick hybrid? E trailer has a YouTube video however this doesn’t show how the connection was actually made to the jumper post. Thanks.

If you flip up the cover on the positive battery terminal of your Ford Maverick Hybrid you'll be able to access the post that will allow you to attach the ring terminal of the Towed Vehicle Battery Charge Kit part # DM66VR to it.

Part Number: DM66VR Towed Vehicle Battery Charge Line Kit for Demco Air Force One and Stay-IN-Play Duo Braking Systems I had the item professionally installed by a recommended eTrailer service center After hooking up the charge wire to the positive post, i still don't get a charge my (2024 Ford Maverick Hybrid) from my RV my battery is dead after 3 hours of travel. 7-Pin from RV has 12V Aux - 6-pin to Maverick gets the 12V Wires are fused Using Demco Stay & Play Maverick in Neutral Tow as Ford describes Charge line visually loomed and in good shape What am I missing?

@StillM Does your Maverick happen to have a different type of battery like a lithium battery? Have you tested the wire that runs to the battery for voltage?
