i hooked up my greddy tt but i cant find which wire is the speed sensor wire. i have a chiltons manual and all that it tells me is that the wire is yellow but there are like 5 wires.any of you guys know which one it is?

 

You dont need to hook that up. I didnt on mine

 

i know it works fine without it but it has a speed feature so it will tell you youre timed runs and stuff like that.
