2005 GMC Canyon VSS Wire

Trying to install the AVIC-N2 and says it need the VSS wire for the navi.  Need help finding it or knowing if it even has one.  Please help

You can find the VSS wire @ the PCM under the hood on the pass firewall. The wire you want is yellow/black and it will be in pin 25. There are 2 yellow/black wires in that plug so make sure you grab the right one. If you can access the pins, the one you want will be between a dark green & a RED / black wire. If you have no luck with that, the sensor itself is a 2 pin off the trans with a purple wire and a yellow wire. Not sure if you'll get the reading you want off of those, so try the PCM first. Mike
