3rd Gen. Firewall tips?

Hey guys! First post here, not sure the format to use. I'm looking for advice or tips on running wiring through the firewall, I want to avoid cutting or trimming anything at all. Not sure if Bluetooth options are any good, but I feel keeping it analog is the way to go. I am looking to run several wires through the firewall in the future. If you have videos, tips, or any advice on how you did it, I would greatly appreciate it.

 

You can grab the hole on the driver's side that comes through under by where the fuse box is. Coat hanger and tap will do

 

You can also use the grommet on the passenger side where the A/C drain hose is. I've run my coax cable and the wires for my motorized antenna mount through there.

 

Yep, it's pretty easy to come through the gromet on the drivers side, above the kick panel.

 

I ran all my cables through the grommet on the driver side. I sliced the hole bigger because I have so many wires feeding in, but I imagine you can pull some wires through without slicing it open pretty easily.

 

Get an Spod and only do it once

 

There's a hole right next to the brake master on the firewall where you can pop out the plug and slip in IIRC a 5/8" rubber grommet. I did this and ran a bunch of wires for my Switch Pros.

 

Wait- what type of wires? Small guage or power cables?

 

I am looking to run several lighting wires, probably 3-5, and eventually radio. The antenna will be out back so I can just go through the floor? Seen a video or two doing that, not sure if its a good idea for the long run.

 

Lighting wires should be pretty small, you'll have no issues going through the driver side firewall grommet. I have several lighting/switch wires, a 0guage power wire, and some ground wires going through it. For your CB antenna, you'll probably want to go through a floor grommet and run the wire under the cab. I went through the grommet that is under the passenger seat and ran it along the frame to the back of my bed.
