Ok, more Questions. What colour wire does the NX TPS switch connect to at the TPS sensor. Also where so I get the RPM signal for the 685 box?
Thanks

The white one.
Where do I get the RPM signal for the 685 box?
The coil, I would get the MSD harness. That way you do not need to cut the factory harness.
MSD harness part# for my 93-95 (dual connector) coil is MSD-8876.
96-97 (single connector) coil harness part# is MSD-8877.
Connecting MSD harness to Mallory Harness MSD to Mallory:
(MSD)Red to (MALLORY)Red
(MSD)Black to (MALLORY)Black
(MSD)White to (MALLORY)Green
(MSD)Orange to (MALLORY)Yellow

Thanks Mr_Bond!!!!! Thats the answer i was looking for. The 685 box i bought from "jakesz28" has the MSD harness with it.
Next question. How did you wire your system? I've looked at ALOT of diagrams and there not all the same. I would like to only retard the time when the safety's are made, and the no2 is on it's way, not when i arm the system. I have a FPSS,remote bottle opener and a heater with a tempsensor and pressure sensor.
The reason I'm asking all these questions is because i bought the system used.
Thanks

These two should help you with the wiring, just sub the TPS part for the WOT switch

Just hook the timing retard wire (not sure what color I'd have to look) to the power for the noids. So when they get power, timing is pulled.

Now that I have the kit the drawings make more sense!!!! I also have a bottle warmer with a pressure switch and gauge. As near as I can tell you run the key power from the on/off switch through the pressure switch and use it to close the relay to put 12V to the heater?
