Need a Good Ground

I am hooking up my LM1 wide band O2 sensor on a semi-permanent basis. I found a switched hot lead in the fuse box I can use. However, a good ground was not so obvious.

What are you guys' suggestions for a ground near the fuse box so I can run my hot and ground wires somewhat close together?

Thanks much.

I really don't want to put a hole in the firewall. But... I have a hand drill and I'm not afraid to use it!

look for the dash ground. mine is on the driver side behind the kick panel i think, but it could be a little higher.

I've used one of the nuts that holds the steering column to the floor. Seemed to work OK.

Thanks all. I'm remaining calm and stepping away from the hand drill.

I noticed the bolts holding the steering column to the floor. The threads are actually on the inside of the car. If I put a connector on my ground wire, slip it over the protruding threads and tighten another nut on top of it, all should be well.

I wanted something that was semi permanent and I did not like the idea of Velcro on my dash or anywhere else in my interior. I fabricated a carbon epoxy bracket as shown, metal would work as well. I put Velcro on the back of the LM-1 and top of bracket. The side of the bracket slips in between the seat and console.

Thanks for the good advice on the ground!

I used the steering column mounting bolt and it works great.
