On pass. side there is a large black grommet, it has the antenna wire running through it. Take it out then theres room to run more wires, get a new grommet so your wires dont get tore up!

well we dont know what kind of truck you have, but on 1st gens, follow the parking brake release cable to the firewall, there is a big hole, with foam glued on. push through and theres plenty of room to run wires. Im not really sure if i should be greatful, or mad that its so easy, and nothing better fitting.

You just have to be careful doing that on a second gen. that grommet is REALLY close to the exhaust manifold, so working down there is crampt, and can get warm, so make sure your truck has been off fo awhile, and make sure that you use wiring that can withstand the heat as well...
