Help Needed - HZJ79 gauge cluster - speedo and tach

[gifu]

2002 (ish) HZJ79.
Gauge cluster from Oz.
I need to figure out the wiring for the tachometer and Electronic Speedo.

What I have figured out so far for Speedo:
sending unit is same as 80-series. So, guessing it works similar... one wire in from cluster, one wire out to ground, one wire from switched 12-volt.
Speedo question: which wire is input on the cluster itself?

What I have figured out on the tachometer:
sending unit is on the IP. two wires coming from it. I'm guessing one goes to ground the other goes to the cluster? or is one switched power and the other going to cluster? And which wire or position is it on the cluster? pretty sure it's the blue (middle) position on the cluster.

Heeeeeeeeelp...

OK.. never mind. I'm now cross-eyed... but after hours of reading through a the service manual... I figured it out on my own. I'm all grown up now.

For reference... the middle blue plug (2001-2006 or so) is "C13". The tach is pin #12 (called out as ECM but whatever). The tach sender attaches to this wire and then to ground.
The speedo is C13 pin#10. There are three wires to the speedo sensor... if you look at the plug, it's 1, 2, 3 from left to right.
1: Power
2:ground
3: signal to C13-#10

Whew.

so was this basically plug in and play?
My 79 just has the speedo, fuel and temp.
I'm hoping to essentially get the aussie (Dual fuel, tach, speedo, temp and fuel) all into the housing.
Just need to figure out what I need to do this.

My harness had the wires. But I had to hunt and peck for them
