You cant use the vss. There are 4 wires for vss at the BCM and all of them are not alternating current. The Pioneer navs work great with out vss. Pioneer claims that not having the vss wire connected changes the accuracy by 3 feet. Witch is nothing.
Thank you for the reply! My install is just about done then. That was the only issue holding me up. Thanks again.
Looking for the VSS wire in a 2008 Ford Fusion. Anyone know it's location or color scheme? Also, has any heard about the Fusion using data instead of a signal? I was reading that even if you find the VSS, the receiver will not pickup the signal? I'm not sure if this is true. How about you Soundman, have you installed any of these units in a Fusion?
