need input snowmobile trailer wiring.

I need some good input. I am trying to get everything with my sleds ready for the winter. Last winter I added a 12v battery to my A/C sled (added rectifier and rewired the headlights to the battery, along with some other lighting). My wife's sled is already set up with a battery. What I am thinking of doing is changing out the 4 pin trailer plug for a 7 pin and using the power/ground to connect some type of connector that I will mount on the trailer (I am thinking an outdoor household outlet). Then making a harness that I can quickly connect to the batteries and plug into the connection for while I am towing. I am hoping that by connecting the batteries to the truck, I will be able to charge the 2 small batteries while I am towing. Can anyone forsee any issues with this, or have any input? thanks in advance. KennyKenny

i know that napa has a two pin quick disconnect that looks like the four pin trailer plug, grab two sets and a 7 pin set and some heavy guage wire and run the center pin(i think) down the tongue and leave some extra to go under the seat and just install your two pin plug up to the battery under there, hope this helps

The only thing I would add is that if you have spice any wires together, do the rielable solder and heatshrink, but tie the wires together first. I always do this with any trailer I work on and have never had problem yet, butt connector, t-'junk', even just solder (cracking) can fail with the constant bounce of a trialer. What I'm talking about is strip the jacket of about 1 inch twist each wire clockwise, then square knot them & solder. I learn this from a nam demolition vet. Good advise from an uncoventional source.
