Calling all electricians!
Not sure where to post this so here goes. We purchased a 8.5 x 16 enclosed trailer to haul toys and work stuff. I bought the trailer with the RV style side door so we could use it from inside.
I recently put a box on front and mounted a deep cell battery with the intention of being able to run lights just like in our Mountaineer. I have purchased a central switch with six switches on it to control lights etc.
In order to charge the battery from the 7 pin power plug, what would be the best way to wire it and then hook back into the trailer interior lights? Do I simply splice into the hot wire in the plug near the emergency brake and then run it back to that line or what? Any suggestions would be appreciated.
