The purge has no connection to the FJO controller. Purge is just a switch to relay/solenoid for the purge solenoid action. The FJO has two usable controllable outputs. For my C5 I wired a supply power relay to one wire from each of the fuel/nitrous solenoids. This will be the +12 volt source for those solenoids. Then the FJO is connected to the other two fuel/nitrous wires and will control the ground side of the solenoids. You will then go through the software fo the FJO and setup the contro, ramp that works best for you.

What are you wanting to use for your TPS and RPM signal?
I personally used a micro switch under my gas pedal for the TPS since I did not want to tap more wires than I had to. For the RPM I pulled the signal from the computer connection mounted in the fender under the battery. As for the other connections I just wired the arm switch into the input of the FJO and to the nitrous solenoid relay. The noids connect to stage 1 or stage 2 (depending on how many kits you are running) and the output from the relay. I mounted my FJO in the glove box and grounded it to the dash frame. If you are looking for more info just ask.
