Dec 02, 2011As a matter of fact, the wire to the ECM is the same color on the DRAC as earlier (pre-'90) VSS setups, brown. The other two wires might be same color, no big deal, the pinout is as I posted. The other two VSS inputs are off of the t-case or tranny, same connector, and the wiring will match up with the DRAC wiring.

Sep 27, 2010The VSS signal comes from the trans, to the DRAC and then to the dash. Check the wiring and the power to the DRAC. If you don't have wire diagrams, you can get them from Autozone. If all is still connected, the T5 VSS sender is bad. The other thing to check is that the reluctor is visible behind the sender on the tail on the trans.
