I installed a bull bar with fog lights & I have to run wiring from under the hood into the cab to the switch, where is the best place to run them? On my 2000 Ranger it had a rubber plug in the "A" pillar that I ran wiring into the cab but I do not see any on the F150. Any ideas or suggestions?

 

My wife's 09 Navigator had a grommet just to the right of the brake booster that I was able to stuff an oil pressure sensor wire through.

 

On my 2004 Lariat there is a 3" circular rubber plug in firewall on engine side behind accelerator pedal. I had to pull the carpet back and remove precut 3” circular interior insulation behind rubber plug.

 

Thanks guys for the info. Looking at the firewall just to the left of the brake booster is a big rubber plug, I removed & cut a slit in it & pushed the wiring thru it & reinstalled the plug. With the rubber plug out of the firewall I pushed a long screwdriver thru the insulation, then from inside I pulled the precut piece of insulation off. Worked great.
