HSW Interface wiring question I have an interface I wired into my friends nitrous setup and have a question on it. It pulls timing like it should, only at wot, only between the pills set on the window switch but it pulls timing even when the system is off. Looking at the interface itself the spray LED is on at wot on motor. Everything is plug in except one wire going to the window switch and another going to the noid relay. How do I fix this problem?

Page 5 of the interface instructions, interface with rpm window switch wiring diagram. Has grey to iat, blue to window switch, brown to the ground on the relay, and white to pcm which I didnt use since I am not using top end fueling.

That "shouldn't" matter (85/86 being switched).
Check to make sure the ground from the Interface isn't shorted somewhere.
What are the settings on the interface? Make sure you don't have some sort of "zero fault" in the settings that would allow it to always pull timing?
Wait... I'm an idiot... None of that wiring we just discussed would be suspect if it's pulling timing but the noid isn't being activated as long as it's wired up per that diagram.
