Default New NOS power relay?

After studying the manual that came with my NOS 05177 dry kit, I set about to start the wiring. I have an MSD window switch so someone here posted a slightly modified version of NOS's diagram for me.



But when I was just about to start, I happened to actually read the instructions for the new 30 amp NOS relay that I recently bought. Apparently the 05177 diagram that we're familiar with is obsolete and has been replaced with this one.
http://www.holley.com/data/Products/...A5088-SNOS.pdf

So now how do I wire in the window switch? I was going to connect the yellow wire from the window switch to the WOT switch terminal that would normally be for the WOT switch ground, but now the WOT switch doesn't have a ground. Instead, that terminal is now wired to the arming switch. Should I hook the yellow wire to the ground terminal for the arming switch? Or maybe hook it up to the green wire from the relay? Any ideas?

The original still fine- Its a warning for previous installed systems- Just pick one or the other-
You could tie the yellow wire to the green ground from the relay- providing a path to ground when the MSD is active
Connecting to the Arming switch wont due anything- but turn your light on the switch in when its active

oh contrare...
I do not advise running that fpss on the ground of the relays. They aren't rated for that much current.. which will slow them down or not operate. Yes, people have done it.. but way not a good idea.
Put it in line with the WOT switch. (low current side).

I'm not going to ground the fpss through the relay, I'm grounding it through the solenoids, just like in the diagrams.
