Well, if that wire is pulling the relay coil to ground even when you're not in RS mode, then it's not going to work as planned.
In general, to see what a signal wire does, I'd start by first measuring its voltage, referenced to ground, to see if it puts out any voltage or acts strictly as a closure to ground. If you don't see any voltage in any conditions, then it should be safe to try putting your dmm in resistance mode and check for continuity to ground, again under all the various conditions.
I expected that "ground while RS" signal to show continuity to ground while in RS mode, and then go open circuit when it's disabled, but apparently that's not the case.
When you did your test on it with the separate relay, connected to the signal and 12V, hearing it click in, were you able to try a RS cycle to see if it clicked off at any point? Unlikely as it seems, maybe that output is bad too, like you found with your ACC output- it should at least toggle at some point; otherwise, it's kind of a useless signal, isn't it?

...for the ground out wire, my meter read 2.2 on the 200m dc voltage range...
Why can't we edit posts here?! lol... At least give us one extra shot to get our posts right

Yeah, it'd be nice to be able to edit- every time I'm about to click on the submit button, I feel like Regis just asked me, "Final Answer?" 
haw!
Hmmm- how many relays do you have hooked up to the GWRS signal? Might want to do a quick check to make sure you're not exceeding the current sinking capability of the output; since each of your heavy duty relays might be drawing quite a bit.
If you could find some other signal that only goes active when you're in RS mode, you can use that to control the latching relay.
In any case, that GWRS signal's not going to work out, if it clicks on your relay even when you're not in RS mode. Off to Plan C, I guess....

I have three relays including the K1 in the diagram...
I'm glad your helping me out with this as I would have given up long ago, lol... 
Thank you!
