Hey I was wondering in the NOS Drive by wire #15972nos do you connect the Ignition Signal to the RPM Signal? And Do you connect the TPS Signal to somewhere in the engine bay near the wires that connects to the Trottle Body? If so which one.

-Yes you need to connect the Ignition Input wire to RPM signal.

-You need to hook the TPS sensor wire to the throttle position output wire on the throttle body. There are 2 which give a positive voltage ranging from 1-5 volts usually, not quite sure what the Tc's voltage is. Any-who.. pick either the Brown or Light Green wire and verify by probing with a multimeter. Have someone press the gas pedal down slowly and you should see the voltage sweep from up to down and down to up.. yada yada.. you get the picture. But that's your TPS output wire your NOS switch needs to know when you have the gas pedal mashed to the floor so it will activate the solenoid for the go juice. Oh here's a diagram just in case... Remember VTA1 or VTA2.... good luck

Why is it that when I connect the PRM wire to my Autometer tach it doesn't work?

Which wire are you splicing into for the RPM signal?
