I purchased an electrical boost guage some time ago and have delayed installing it for lack of way to route the tubing and wires into the engine bay. I could drill through my firewall, which I absolutly don't want to do, but it seems there would have to be a better way.

I can see no existing holes in the driver or passenger firewalls for me to run the required accessories.

One person told me that I could take out the inner fender liner on the driver's side front wheel well and have access to a small hole, but the fender liner is stapled in from the factory, and I don't want to rip the staples out.

For those that have installed your own boost guage, and/or other guages, how have you ran the cables and tubing?

Any insight would be appreciated.

Thanks.

electronic boost gauges will only require you to run wires into the cabin of the car. I ran mine through the hole that mentioned behind the fender. The staples are not holding the plastic to the metal. there are multiple plastic pieces stapled together, they have to do with the vent behind the front wheel. you will be able to put it back together just like it came from the factory (or at least should have come with that new boost gauge installed)

 

I ran mine on the passenger side firewall, where the a/c lines run into the cab. I pushed the plastic away and ran it there.

 

I drilled. But that's because I didn't ask like you have. I would do the fender trick if I could do it all over.

 

I don't remember the fender liner being stapled to anything but more fender liner pieces. I think the various trim clips and screws hold it in, not the staples. then it's relatively easy to get to the access holes. I just fed my hose through the hole directly under the cruise control, or (R1) Next to the Brake Master Cylinder in the inner fender. Then there is a hole to the cabin through some penetrable rubber. It winds up coming out right by the fuse box, IIRC, by the driver's foot. It's really easy.

 

I drilled as well, but like stated above, I would have used the fender opening if I had known about it. The fender liners are easy to get out. No staple pulling needed.
