Firewall Holes???

What firewall holes to use when installing additional gauges??:confused:

Looks like a tough one for AutoMeter Vac/Press and Fuel pressure which both use a large plug....require a 1" hole in the firewall!!:argue:

:help:

Thanks!!

I had to run some wires for the remote start and GPS unit, don't remember seeing any large unused holes / grommets. May have to drill you own......

I put a hole in my floor and ran both sets of wires thru one grommet. Glued the grommet in place with silicone 'cause it kept slipping out. Gotta have the big hole because of the connectors on the electronic gauges. I put the hole on the driver's side near the master cylinder. Drilled a small hole then used a Greenlee punch to make a nice, neat hole.
