Stop Battery Drain While Towing 2020 Honda Civic Behind Motorhome
Question:
i bought your towing kit and lights kit and just had it installed. Now, in order to unlock the steering column I need to at least put the car in ACC mode. will this kill the battery? What other options do i have?

To prevent your 2020 Honda Civic coupe (with manual transmission) battery from draining while towed you need a Roadmaster # RM-156-25 Battery Charge Line Kit. This line runs from your Honda's battery to the center post of your six pin connector on the front of your Honda. You installed this 6-pin connector as part of your previous install of the Roadmaster RM-15267 kit. I have attached a link to the charge line kit page and to an installation video.
When you have the 6-pin connector boot off and have finished installing the battery line I would coat those connection posts with dielectric grease # 11755 to keep moisture and grime out.
If the 12-volt pin of the lighting connector on your motorhome does not have 12 volts to it you will additionally need Roadmaster Battery Charge Line Kit # RM-156-75 which runs from the motorhome battery to the 7 pin connection on the back.
I have attached the "pin out" wiring diagram for your 7-pin connector.
