Anyone out there have the factory auxillary battery setup working in the Blazer or F.S. Truck. The option code is 1TP2.

I have a schematic in the back of my service manual. I have a relatively small gauge wire red, coming from a switch on the firewall. The wire from the switch goes to the starter.

I have the factory aux battery tray. I assume to hook it up I'd run a wire to ground and connect the red wire to battery positive.

I assume my alternator will charge both batteries. The aux battery can be used for winch(need $$'s) and trail lights.

I got a new bumper being built by Kennesaw Mountain Accessories with grill guard, brush guard and recessed Pro comps, so a winch is in my future.

Appreciate your comments and/or pics
