TKO 600 speed sensor hookup

[Tom Vogel]

Anyone using a TKO 600 with an AAW classic update wiring harness? If so, where does the VSS variable speed sensor power wire go to? On the AAW classic update kit it is the purple/white wire. AAW says it goes to the speed sensor, but there are only two wires coming out of that sensor, and they are already hooked up to the yellow and purple wires which are the signal wires.
Any ideas where the power wire goes to? AAW didnt know.
