N20 Switch wiring with OS5

[BowlingSS]

Can I hook my N20 wire(PCM Pin 56) directly to my N20 switch so when the switch is on Pin 56 goes to ground? I am trying to save a switch.

Thanks,
Bill

Bill,
You are going to need a double pull, double throw relay. One side of the contacts will provide power for the noids, the other side ground, for pin 56.


You will need something like this....

12vdc, plenty of current for the noids, DPDT=double pull, double throw.

Hint, it fits nicely behind your radio in the little niche brought to you by the factory if you use a spare fog lamp switch for the whole setup.

Here is the wiring I used to Earth Pin56 whenever you arm the nitrous.

Easier to explain in a diagram.

What size relay are you using?

Bill let me know how it works and if the spreadsheet is accurate. Your going to beat me to testing it by a couple of weeks.

I will write up a N2O COS5 tutorial from our lessons learned :cheers:
