I'm gonna run a PA with my CB (yes, we still use em) and wanna find the most painless, easiest route thru the firewall of my 2009 F-150. Presuming Driver's side, and following a wire harness grouping.

Suggestions?

I installed a ham radio setup today in my 2010. On the passenger side on the firewall there are 3 big electrical plugs a little below them is a small rubber plug that is where I ran my wires and coax. I pulled the plug cut a hole in the insulation and fed the wires through it is very tight because of the fan motor and duct work. I pushed a lot of coax through and then used a 24" claw tool and a flashlight grabbed the coax and pulled it through and did the same with the power wires.

 

Driver side, to the right and above the steering column. Kinda between the brake and gas pedals. There's a heat shield on the interior, but you should be able to see it from the hood side.

I've got a ~3" diameter bundle running through there. I do run the entire thing in heavy split loom to protect it.

 

I ran wires through that hole on the driver's side. The grommet pops out easily and I was able to cut a slit in it with a pocket knife. I left the outside diameter edge uncut so it would still seal up the hole well.

 

Thanks folks!! I'll look for those locations.
