ford gen 2

I just purchased used 08 F250 super duty with the Gen 2 system. After traceing wires I need more info such as fobs, activation of system. I found a push button under steering wheel under dash, little marker light by headlight switch. Would like to see if it works, what fobs I need, what is already installed and what it controls, wiring diagram. any help would be helpful.

This is the entire diagram chart and install manual for the gen2 system. https://www.the12volt.com/addfile/files.asp?s=2462827&f=2009%5FGold%5FRemote%5FStart%5FTruck%5F09%5F04%5F2009%2EpdfGary Sather

Thank you for the help I was wondering tho where to get the parts like replacement fobs and such.

Your local audiovox or codealarm dealer should be able to order parts for you..Gary Sather
