    What is the simplest way to run a new aux battery ground cable to the frame? I'm using #2 AWG cable with copper lugs. Would a large self tapping screw work? :help:

    This is for an auxiliary battery in the bed of my truck, not the primary starting battery. Thanks in advance.

    I would drill a hole, clean both front and backsides of any paint, use a bolt with a nut and a star washer against the frame on the backside and lug against the frame on front.

    I always use copper bolts, nuts and washers also. A little locktight is also good.

    Sounds cool, If it is going to be hooked up to main battery, why not tie into main battery ground wire?

    It's a separate battery located in the rear of the vehicle. Frame is common ground.

    Thanks. Drilling a hole it is then. I'll have to go find a cobalt drill bit to do the work. :)

    On my rig, there is a factory ground at the rear of the truck. Look at the frame behind the drivers side rear wheel. I just hooked my battery up to it yesterday.

    Why would you drill a new hole when there are plenty of bolts that you can use instead of wasting time and money?

    I made the thread before I inspected the frame. So it was from a theoretical point of view. As it turns out, there is a 3/8 hole on the passenger side near the wheel well that's perfect for my application.
