Looking to add a simple dry shot with a Nitrous Outlet halo to my car for some added fun once in a while / track use. I've always found the HSW Interface controller pretty interesting, and was able to find one unused that I'd like to use for fuel adjustment (I have a wideband to see afr) until I get hptuners and learn to tune it. I have a Nitrous Outlet Winmax and am unsure on one piece of the wiring it with the Interface. Where I'm getting stuck is the Interface Triggered Input on the 2 diagrams I mapped out. Since the Interface is old, it's been hard finding anything recent about wiring it.
My idea is to use the Interface as the timing controller so there's less stuff to manage, but would be fine using my lnc-2000 to control timing if it makes it easier.
Interface Wiring Instructions:
Brown - Triggered Ground Output
Blue - Triggered Input
Grey - IAT / Timing Retard
White - Top End Fueling (not used in both diagrams)
Here are my 2 wiring diagrams.
Diagram 1: Winmax + Interface: Interface controlling timing on small shot to pull preset 3 degrees for ~75hp
Diagram 2: Winmax + Interface + lnc-2000: lnc-2000 controlling timing for any size shot
Any feedback would be great.
I think the 2nd diagram would be best. But, I think you need to get rid of the brown wire all together. You're wanting the Winmax to trigger the relay and not the interface right?

I believe so. I found this image from an old thread and wasn't sure if both wires were used or not. Looking at all the diagram and instructions below, should the interface trigger wire (blue) be tied into the blue winmax wire then the interface ground (brown) go to 86 on the relay?
Here are the instructions I got with the interface, I tried matching it up with the winmax instructions and got lost since I can't find anything consistent lol
