Cxu Hook Up Lamp

[cxn613]

Installing a hook up lamp on our 2008 cxu. We bought the light and new switch panel that has the button for the hook up lamp. Dealer tells us there should be a wire or two somewhere around the clutch pedal that you hook a harness you buy through Mack that goes to the hook up light, or can we just connect two of our own wires to the ones under the dash and run them to the light? I already have the panel behind the seats out and the hookup light in the cab is installed, we just need to know what wires under the dash to connect to. The only two that is seen with plug ends on not being used is one that is labeled "bat aux" and one labeled "ign. aux" and then theres one that says "cxu only" "chu only" and "gu only", i'v installed the fuse for the hook up lamp, but there is no power at either of these wire ends. Any help will be great. Thank you
