autometer electric speedometer sending unit.

I just bought new classic electric autometer gauges for my 96 stang. I got a whole set for about $250, including oil pressure, water temp. volts, fuel level and speedometer. I was wondering if anyone has installed an electric autometer speedometer in there sn95. I need to know if I can use my OEM VSS (vehicle speed sensor) that comes on my T5 tranny or do I have to use the aftermarket one that came with the kit. the wiring is very confusing to me so if anyone could help that would be great! :shrug:
 
Hello,

i bought a autometer vss for my tremec but it was to bulky. It interfered with the tranny support. Then i wired my stock (89gt, a9l) vss in.
I use number 3 (+vss, dark/green) for the signal and my autometer speedo works great.
