Reverse lights always on

[Old462]

A couple of days ago, the reverse/back-up lights on my truck came on, and have been on since, when the ignition is in the ON/RUN position. My Haynes manual is no use, and I haven't torn the dash apart far enough to get to a switch on the back of the gear selector - I've had the driver's side dash off, and the instrument cluster out, but to get farther back where that switch might be, the entire dash would need to come out. Not sure I want to tackle that. Does anyone know where I might be able to find a specific wiring diagram for my truck online? I know the dealer would have one, but who knows what they might charge for that, let alone do the work. Has anyone else had this same problem? I'm fairly handy with a meter and leads, so doing the work is no problem, I just need the wiring road map.

Thanks y'all.

DOH! Yeah, I should've included that. Thanks. Yes, it's an automatic. Zoodad mod, otherwise stock, if you don't count installing the XM radio. 2007 KR CC LB auto.
