Hello,
New Ram owner -- 2004 with 5.7 Hemi, factory tow package. It has an electronic brake controller and a 7-pin harness connector.
We will be towing a travel trailer and doing a lot of boondocking. Is it necessary to unplug the trailer wiring harness/umbilical/pigtail from the truck to avoid draining the truck's battery while using 12 volt lights and appliances in the trailer? (The trailer has it's own battery.)
I've heard that in most vehicles, current will continue to flow through the wiring harness, from the truck to the trailer, even with the key off. But some vehicles have an automatic, built-in feature that prevents this from happening.
Thanks in advance for your help.
