RPM and TPS wire taps...

[jb4lsu]

So I am getting close to having to wire up my FJO nitrous controller and have been reading up on where to tap into these wires, and have have read different things...

For the TPS, I am seeing the best spot is to take this signal from the gas pedal instead of the throttle body itself. 2nd wire closes to the drivers seat, got it. Right?

For the RPM signal I see some people using the injectors and some coming off the coil, as well as using cylinders 3, 7 and 8. So what is the one I need to use?

Any help is appreciated!

Thanks!

You are correct with the TPS signal location and I would recommend going from the injector as trying to get the signal from the coil pack did not work for me.

Is that tps wire u speak of falling voltage or rising? I hear we need the falling voltage wire for a smooth voltagr sweep
