[Lee00blacksilverGTS]

I am posting this for a poor soul who has been trying to register but is having trouble with a corporate email. here goes...Anybody help this guy.
-----------------------------------------------------------------------
I do not own a Viper.. I am using a Viper T56 behind my LS1 that is being swapped into my 71 Chevelle.. need to modify the VSS to work with the LS1 PCM. 1) get it wire to work or 2) be able to swap in a GM VSS into the Viper Tailshaft.
The info I am trying to find it the Wiring of the VSS sensor, there are three wire and not color coded !.. which one is which ( neg, pos, output pulse ?)

The skip-shift fixes are the same if that tells you anything. The one in my car was listed for a TransAm.

The '94 service manual shows three different wires.

With the nub of the plug upward, the left wire is white/orange and is the VSS signal into the PCM.

The center wire is black/light blue and is the ground.

The right wire is an 8V supply from the PCM and is red.
