going through the firewall

[KDRacing]

getting ready to do a set of gauges in my truck, was just wondering what the cleanest way to get through the firewall is on these trucks. I was hoping to get lucky and not have to drill but i didn't really see any easy way through. If i end up having to drill whats the best way to seal up the extra room? or should i put a grommet in? any pics would be great... trucks an 03 6 speed

On my '01, there was a large diameter grommet already there. They (install shop) ran the gauge wires through it. IIRC, it's on the vertical part of the firewall to the left of the brake pedal. In my insulation up there, there is a pull-out piece already cut into the insulation. Just pull out the 'cover' (if you will) and the grommet is behind it.

thanks for the help, ill take another look... maybe i just missed it.

If your truck has an Auto trans, there's a plug where the clutch rod goes through firewall, it's a convenient way through....

That's probably what mine is then - His is a 6-spd.

i was gonna say i went and looked again after work and didn't see anything like what you were talking about... actually i have clutch linkage going through a rather large cut out right were you described lol... so much for that

On my 2000 there is a large plug under the carpet right where your feet rest. I used it to run my amplifier power wire. Just remove the drivers side kick panel, the plastic panel that runs along the sil and pull the carpet up... can't miss it.

on mine, i poked a whole through an existing grommet on the firewall, if i remember correctly its above the brake pedal and almost behind the dash, but still accessible. i used a clothes hanger and a lot of cussing but got wires through for my fog lights. in all honesty i would think it almost easier to drill a new whole out and put a grommet in it, that way you have a fresh whole (however big you desire) to put however many wires through that it can handle.

I have a 6 speed and ran into the same issue. I bought a box of grommets and plugs to use. A plug is just a grommet that is filled in. I used one of them because it made for a much better seal. I just poked a hole in it and pulled the wires through. Search amazon for grommets and plugs. The one I bought was $12 with no tax and free shipping. Good luck

I used a Rotabroach to cut a hole in my firewall. Leaves a nice clean hole, much better than a drill bit or hole saw.
