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...jsnone1 said: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!
