Im installing a Pioneer Avic N1 in a 2009 Dodge ram 1500 (automatic, Hemi) and I need color/location of the speed sensor wire

a local shop told me the dark GREEN/ brown wire but with this wire hooked up the speed is 9 to 10x high (30mph shows 275mph on the nav screen:o):

Is there a special lead for the vss connection like for the reverse indicator? because im using a regular 22gauge wire

any help will be greatly appreciated

It was on the ECM on the passenger side firewall. The connector on the right(closest to the drivers side)
