Front mounted battery - looking for good grounding point

[Henrik]

I am moving the battery to the front. Can anyone recommend a good, solid grounding point on the right side, below the trunk?

Thanks,

Henrik

Why?

I believe the easiest would be to go down to a bolt on the fuel tank retainer/cover. One of those would have sufficient contact to the frame for the grounding.

I would use any of:

• the M6 bolt(s) holding the upper radiator support bracket to the frame
• the M8 bolt(s) holding the lower radiator support bracket to the frame
• the LH-mounted M6 bolt holding the brake tee to the frame

I would not use any bolts that secure suspension components; i.e., the M12 nuts securing upper/lower control arms or the M10 bolts securing the anti-roll bar.

I drilled into my frame and used a bolt and nut to make a ground for my headlights. I cleaned the epoxy off that area and after I bolted on the ground lug, I painted right over everything.

Note:
Your stock headlight ground has two 12 AWG wires in the harness running back to the ground feed through in the relay compartment. Using frame ground for the headlights opened those two 12 AWG wires for other uses. I used one to get 12 volt battery power to my side blinker circuit.

Several of us have run 4 gauge ground buses through our cars. We tie into the battery in its stock location, but could do the same anywhere else in the vehicle.

Well, turns out my biggest challenge is not running the 1 gauge wire from front to back (I threaded a test wire along the AC lines with no problem) or finding a good grounding point in the front: The hardest part seems to be finding a spot in the trunk where the battery can be properly secured without impeding access to the brake fluid reservoir, clutch cylinder or the spare wheel. The only place seems to be the right rear corner but there is not enough floor area to mount it securely.... If anything, I'm considering a sub-floor to mount the battery to, which in turn is bolted the trunk. I might be able to make the sub-floor narrow enough that the spare wheel can slide in and out. We'll see...

There is lots of room under the trunk floor. I would cut out the floor and make a little pocket for the battery to sit in.

1 gauge wire

Can you spell "overkill"? Exactly how powerful is your subwoofer?

Good one! I'll have to look into that possibility.
