I found the location of the factory installed amp. It's behind the passenger kick panel. What i'm looking for now is the wiring of the plugs on the amp. There are two plugs and many wires. I'm trying to install an after market radio. Any help will be appreciated. Thanks

 

See if you can find a copy of the factory service manual for your truck. That's the best way to do it, and then you have the information available, any time you need it. (and then some.)

 

This is the wiring diagram for the 2005 amp, maybe the wiring colors match up with your 08.
