Hello all,
Trying to get a Renogy DC-DC battery charger configured in my Hawk. This Renogy requires a 12V+ feed for sense (I know there are others that do not require this - well too late for that).
I was kind of surprised to find out that the 7-pin round trailer plug at the hitch has an "always on" 12V+ feed. It is NOT switched. Constant 12V+ whether ignition is on/off/acc. Confirmed via actual testing and literature. So, do any of you smart people out there know of a way to make this always on feed at the 7-pin trailer plug be active only when switched (engine running)? Don't want to run another wire all the way back from fuse box to the trailer plug. I already have 4g wires terminating at the back bumper in an Anderson power plug in this truck. I have seen documentation to switch the internal power outlets from acc-on to always-on just by swapping some fuses. I am hoping that there is something simple like that. The truck is a 2016 RAM 2500. I could tap into the tail lights and get the 12V+ but it kind of defeats the purpose of only getting power with engine on. Thanks in advance......Ozzy
