I've installed OS5 already and I'm looking to wire in the N20 switch. I have a switch that activates the nitrous kit on the car and would like to wire into it so that when I arm the kit the N20 section of the tune file activates. I see that the pin needs to be grounded for activation, but I think the switch is constant grounded and activates via the 12 volt power source, is that correct? In this case is there a way to make it work, or do I need a seperate 2 pole toggle to ground the pcm pin? Thanks.
