Battery kill switch e30 - having a total brain fart at the moment....

EDIT: figured it out, and got over my short-term bout of stupidity.

We had to do some ad-lib electrical repairs at the rallycross yesterday (involving bypassing and rerouting some wires due to damage). Anyhow....now that I'm installing new wiring, having trouble remembering what plugs into where at the kill switch for some incomprehensible reason. 

So I have a 6-post kill switch.

Things that plug into the killswitch smaller  blade-style poles:

1. ground wire (with resistor)

2. small power from battery 

3. small power "out" to ECU (which has a double-pigtail on this end)

So which side/"number" do each attach to on the e30?

I have this reference diagram:

So the ground obviously goes to "1" on the side of the switch with the main battery lug. but the other three don't really match up with what I have otherwise. For instance, of the four blade posts, which one is where the small wire FROM the battery goes? Once I have that one right, the twin pigtail will obviously be the last two.

I literally feel like the dumbest person in the world right now. 

The way I think about it:

Big lugs are in line with the main power feed from your battery to your distribution block

"W or 1" is normally closed and bleeds power off from your alternator. One side goes to the distribution block side of the big lugs. The other side goes to a body ground.

"Z or 2" is normally open and should be the power feed to something that makes the engine run. For example on an older car like in the diagram the coil power is being cut. I'm pretty sure you can also cut ECU power in a newer car for the same effect.

Yeah, I figured it out with multimeter. No idea why I was in such a brain freeze, especially since I set it up in the first place lol
