Hole in Firewall
 

Hey guys, i'm installing a mechanical temperature gauge in my '92 RS. I gotta drill a 7/8" hole somewhere in the fire wall or find another way to route the tube.

I can't decide where the best place to drill this hole is, any suggestions would be great.

thanks,

Kyle

What do you need such a large hole for? How big is the tube?
I would drill the hole on the driver side firewall right above where the inner fender meets the firewall.....most cars have relays mounted above that area so they will hide your new hole.

yea, but how much crap do i have to pull off to get to it?


and the hole has to be 7/8" for the fitting (thats what the instructions said)

thanks deadbird, but do't you have to take the console out to get to there?

NO. Just pull down the carpet a little bit.

If youi're refering to the hole in the tranny tunnel picture... that one required a 2 1/8" hole saw and harness grommet from an 80's nissan. Even if you pick such an odd location... as Dirt noted.. just yank the carpet back some.
