Just had a Pioneer AVIC N3 installed in y truck and the speed pulse doesn't work. i heard that I may need a VSS adaptor...does anyone know?

Thanks for any help.

 

I went to the dealership and used their manual to locate the vss wire and the reverse signal wire (purple and pink from the radio) I have an 06 so the wire color would be different. If you dont want to go to the dealer look up www.avic411.com they have all the answers. Hope this helps..

 

Mine hooked up no problem, but don't remember the wire colors
