You did not mention which engine harness you are using.
The VSS harness section you're referring to runs from the VSS to the engine harness along the firewall. The takeout for the VSS harness is located in that engine harness below the takeout for the VAPS harness, which runs from the VAPS module under the dash through the firewall to a brown 8-pin round male/female connector near the firewall, above the VSS.
The harness connector for the VSS is a 2-pin connector, and the wire color-codes are DG/W (VSS signal) an d O/Y (ground) for all 94-95 Taurus models.
The DG/W harness-lead provides the actual VSS signal used by both the PCM and the VAPS module for the 3.0L SHO, and the PCM, VAPS, and Speed Control Amplifier for the 3.2L SHO.
For the MTX - the DG/W lead goes into the engine harness to Splice S143, which splices to leads for the PCM and VAPS. The O/Y lead goes into the engine harness to Splice S109, which splices to leads for the PCM, VAPS, and Ground G103.
For the ATX - the DG/W lead goes into the engine harness to Splice S143, which splices to leads for the PCM, VAPS, and Speed Control Amplifier. The O/Y lead goes into the engine harness to Splice S109, which splices to leads for the PCM, VAPS, and Ground G103.
Color-code Key:
DG/W - Dark Green / White stripe
O/Y - Orange / Yellow stripe
I see the posts for replacing the VSS, but I need to replace (or rather, install) the small piece of harness from the VSS to the main harness (I assume). The problem is, I can't find anyplace for the VSS to plug into. Where is the wire routed (plug on top of the VSS, 10" of wire, the a plug that goes....where?) This is on a wagon converted to SHO drivetrain. EVTM is no help on this one... TIA.
