I have an RV with a separate "house" battery that runs all of the interior lights, fans, etc.
I want to power the factory radio from the house batter as well, instead of the starter batter.
I figure that there must be multiple power leads in; one for the continuous power (to keep the station memory), one for ignition power so it turns on with the ignition, one for the dash lights so it dims when the dash is dimmed, and maybe more.
Also, is there a power antenna take off on the radio? I need to power an FM modulator so I can feed my DVD/TV sound through the factory radio.
The radio has a harness that must have 20 wires running into it.
Any tips?
