well if you hook the two batterys together pos to pos, neg to neg they will have twice the amps. but you have to hve two identical batteries. maybe a higher amp altenator too

well i have the factory stuff i am just wondering where the extra solenoid is mounted from the factory so it looks original. i got the D3TB 14088-AC solenoid and the plastic standoff from a buddy but he doesnt know if the solenoid mounted next to the starter solenoid or on the drivers inner fender.

I don't have a photo but my old '75 had factory dual batteries. The solenoid was mounted on the driver's inner fender about a foot behind the battery. Hope this helps.

Mine was mounted on the radiator support right next to the second battery.

You really should thow the stock one away and get a newer style. Unless you want to be replacing your batteries every other year.

I got a new-style diode pack type for $40ish at NAPA and it works great.

I know it's asking the obvious but your winch battery is a deep cycle? I mounted my batteries in the bed ahead of the wheel well and used HD cable for my + & -, good crimp on connectors or soldering helps with large cables also.
