    I have installed a second battery and am wondering the best way to wire it. I intend hook both up in parallel and double the amperage for the entrire electrical system. It appears there is a threaded hole for the ground already next to the power steering pump reservoir so ground is no problem. As far as the positive goes, it appears there is no good spot to hook into the positive on the original battery / terminal. I have my plow solenoid on the firewall with the positive lead direct from the battery. Can I simply wire the second battery positive to the original battery positive on the solenoid ?

    If not, is there some type of terminal adapter I can bolt onto the factory battery positive cable ?

    Yes you can install on the plow solenoid. And yes you can buy and install different pos batt ends. All depends upon how much you wanna spend, and how good your wiring skills are.
