i am looking to install my avic d3 in my 2007 new body style silverado crew cab and would like to know where the vss is, i purchased the wiring kit from crutchfield for the door chime and stuff for the non bose stereo. thanks

yel/blk ECM, black 73 pin plug, pin 57

this wire can also be located at either the abs module which is under the truck body next to the gas tank and is the only yellow/ bl at this harness or it can also be located at the juncion block on the floorboard next to the e brake. remove it and turn it over you will see the middle connector contains only one yello / bl. I have used both locations and worked great. a little easier to get to.
