Wiring for added interior accessories

[JCSFPD]

I want to add an interior accessory powered from the bus bar located at the battery. Does anyone know of an easy way to feed a wire through the firewall?

Ham radio ? I ran an antenna wire down thru the passenger side hood hinge..down to the rubber plug with the door wires. Thru with the door wires and into the interior. The door has room and does not close on the wire. This was for an antenna for my stock radio, which has the antenna in the rear side window....useless for me...Now my radio works super.
Good Luck

Last 2 generations had a plastic cap in front of the passenger seat under the carpet about were your right foot would sit. It was a great pass through for an amplifier power wire to the back. I drilled through it and added a rubber grommet...

Look for Upfitters Guide.
There should be 12v power feeds available under dash or in pass side footwell.
