Harlan 2-step Plan of attack

Can I resurrect this thread? lol
I've recently wired up my system like this with the Harlan 2 step and a nitrous kit... using a second relay as my "interrupt relay" on the nitrous's WOT wire.
Everything thing works fine when the car is running, but when the car is shut off and ignition is off I am getting voltage on the yellow wire (ground signal) from the 2 step which causes my 2step indicator light in my car to lightly illuminate.
This only happens when the relay is connected. As soon as I unhook the pigtail from the interrupt relay or remove the 12v battery source to the interrupt relay, its fine.
The only difference on my wiring is that I have 12v battery (constant) to my interrupt relay pin 86. I noticed you guys have 12v switched power to pin 86 from your nitrous arming switch. Is that why? I talked to a few electrical engineers at work and we're thinking it has something to do with a "pull-up" or something else on the circuit board when its powered up and causing a funky state when its not.
Thoughts/comments?
Thanks!
