Wires through Firewall

    Hey guys, I'm trying to run wires through my firewall for some aux. lights on the backrack, etc. The question is, where is the best place to bring the wires through? I'd like the switches in the middle of the cab, near the radio. Would it just be easier to drill a hole then place epoxy to seal it afterwards?

    Thanks a ton guys & gals!

    I take it this is gonna be on the 99 F350?

    There is probably already a grommet on the firewall. It may take some looking to find it, but im willing to bet there is one there you can use.

    If there isnt, then I would drill a hole and buy a rubber grommet to insert in the hole, to help prevent the wires from rubbing against the freshly cut metal, then having a short after the insulation wears through.

    Moonraker, thanks for the help! Yes, it is going to be on the '99 I've got in my sig. I forgot to post it! I'm having a hell of a time trying to remove the radio. you're supposed to be able to use bent coat hangers, but I'm having no luck. Does anyone know any tricks to this? or is there another way to remove the main dash panel? I'm wanting to place the switches where the ESOF dial goes, as i don't have ESOF and it's a blank panel.

    Go to the parts store and get the correct tools for removing the radio. They are 2 horseshoe shaped metal pieces that slip in and the radio will pop right out. Or stop by a Best Buy or the like and slip the kid in the shop $5 to take it out.

    I have taken the radios out of all my ford trucks and i use 4 long skinny screwdrivers that fit into the holes work fine. And for the wires for has Wires that are run through the firewall from the factory for auxillary lights, i think there are 5 of them they are tied off under the dash by the stearing coulum and are black, blue, red white, and brown. On my truck under the engine they were tied of under the fuse box. Hope this helps, Otherwise on my 2000 SD i have drilled through the plastic insert right in front of the break pedal.

    I ran my strob wires through the vents in the back of the cab. Worked great I sealed them with a little silicone to be sure but never any water or noise and no hole when I trade trucks as it has a rubber seal that I didnt hurt

    if its has an auto trans it will have a hole through the firewall already on the upper corner of the drivers side. it is not used with an auto trans at all (just filled with a plug). with a manual trans it will be filled with the clutch setup. i have used this hole to bring in control wires on a number of plow trucks and fire trucks alike.

    I've always found where the factory ran wires through. Usually you can find a grommet around the steering column. I run my wires from the engine bay into the cab, then hook everything up.

    Thanks guys! I ended up finding a grommet in the back of the cab, then ran them under the rocker panel cover that pops up! worked out great!
    My truck is a manual, so the opening for the clutch is taken!
    Thanks again for all the responses guys, i'll post pics as soon as i can!

    Nice Jeff! it'll look really good when it's done. how are you planning on using bolts? use paint to draw a pic!

    Also I've thought about getting 2 more and putting them under the tailgate, then synchronizing all 4 to work together. Apparently you can sync up to 8!! Might order a Whelen Guardian as well.
