Where to run 4 awg wire through firewall?
Hey all,
Well I am installing a system in my truck today and was wondering where the best place to go through the firewall was. I am looking but I see nothing.
It's a 08 Mazda B4000 5 speed 4x4.
Thanks

That looks a little tight even for 8 awg wire. Isn't there anywhere else I could go through? I see like nothing. I am poking a coat hanger through but still nothing makes it all the way through!
Unbolt your fuse box and move it and then drill a hole in the firewall behind it. Put a grommet on and your good to go. Thats what I did, makes life a lot easier running wires for accessories. I need to do another one now though.
I ran both of mine through where the factory wiring harness goes through. Problem is that the plastic cap that seals it from the hood side won't go back on. I think my next project will be to drill a hole and use a grommet
Had the same problem with mine. Kept looking for a place to run the wire safely. (Was going to drill.) As I'm poking around, I find this blob of gummy substance on the firewall. Being curious, I pulled it out.... Previous owner had drilled a hole and the sealed it with something after he sold it.
Works for me!! All I had to do was cram a grommet in there and run the 4ga. Problem solved! Sometimes things just work out for me....
then again, sometimes they don't....

What I woudl recommend if you plan on rewiring speakers and adding in amps and whatnot...
Drill 2 or 3 holes and fill the unused ones with plugs and soem thick rubber to keep the sound out.. And make sure its jsut big enough to push a 0 gauge through.. that way you have plenty of options, and you'll never have to redo everythign later if you plan on runnign mroe thorugh.. helps seperate what you want and dont want split up.

Well for me, the easiest way was through the steering, I kept it away but I am not too worried, I zip tied it down, it should be good. I do agree drilling is the best way but I hate doing it.
Why not just do it the right way and get a freakin drill. It's a truck drilling a little hole in the firewall that no one will ever see isn't going to make a difference and will be a lot safer than putting it besides the steering shaft.
Problem is......is finding a good location where your drill will fit! Even a little more difficult for us manual trans guys.
I plan on taking off my engine compartment fuse box, and seeing if I can drill a good 1" hole there on the firewall. Nice, hidden, cleek location to run wires.
BTW.....I have a total of 7 wires going through my steering grommet.......and have for about 25k. No problems. You use the sound material on the firewall to your advantage.

Shane thats what I did, thats the only way I could find room to get the drill back there to actually drill a hole just like you said. It makes life easier just moving the fuse block out of the way.

i ran it below the electrical box on the driver side firewall.

I'm not sure about the new Rangers, But i found a stock hole behind my driver's side jump seat. I put a hole in the fire wall already between the clutch and brake, but its a bit tricky manuvering it so it doesn't get pinched. I'll be rewiring this week though
There is a factory grommet on the passenger side far up the firewall on the right side, not easy to see it but you can feel what it is, comes out under the blower motor, ran 4 gauge through there with no problem, just cut a slit in the grommet and push the cable though
