Electric Autometer Speedometer
 

I just purchased an autometer electric speedometer and I am not sure which wire I am supposed to tap into off the transmission. I purchased the sending unit but it does not fit the Tremec 3550 transmission. The factory wires are orange and green. Which one do I tap for the signal wire to the gauge. I pulled out the factory cruise control, in turn I eliminated a bunch of wiring from the harness. Any help would be greatly appreciated. Thank You.

Autometer is pretty good about giving detailed instructions with their products, the instructions didn't give any good advice? Never used an electric speedo...
