DO NOT, I repeat, DO NOT try hooking up the Z1 VSS up to any random wire. The GMs are extremely sensitive and will throw trouble codes for simply looking at the truck wrong, and will more than likely have to be reset by the dealership. I highly, highly doubt that there will be a VSS wire behind the radio, in the form that we are used to seeing it (AC voltage as speed increases), being that GM uses a single wire to do OnStar, door chime, illumination, and even turn signal clicking sounds. I can check at work on the tech sheet for your trucks and let you know what it says. Any decent interface m

killcrafter, that one single wire is probably your steering wheel control wire, if equipped. Additionally, did you happen to pick up the 224.99 (MSRP) adapter for your truck, namely the Metra GMOS-LAN-01? That P/N will be different for the bose system, by the way. GMs are all f*cked up and use a data system, so an analog wire for the VSS is asking too much, and probably the reason why they are going out of business. I work in a car audio shop for a living, so give me some more details about what you are working with and i can provide some assistance.... PS. Worked on a 08 Lexus RX400h the
