SAMURAI ELECTRICAL - Fuel and Temp gauges not working, no idiot lights

I've got a seemingly simple issue...  as, I've been removing all catastrophe of wiring from my Sammi.  However, now... I seem to have demo'd something I shoudn't have.  Meaning, the previous owner... had an oddball power or ground that I removed.

... everything else works, (instrument cluster) dash lights and everything that needs to be. However, the instrument clusters fuel and temp gauges aren't registering temp... or that there's fuel in the tank and the idiot lights don't come on when you turn the key to "on".  They did BEFORE I was carefully removing and re-taping the engine bay and under the hood.

DOES ANYONE HAVE, or KNOW... the wiring color for the instrument cluster? Or if there's a hint of a power or ground that I don't have, but need.  There's lots of abandoned wiring under the dash (that I've not touched) with connectors on them, and nothing to plug them into. Some of them even have a "loop wire" in the plug where it's a male spade to male spade bridging two wires. (this is a Samurai with an upgraded engine to a Geo Tracker motor/tranny).

I know this is something simple, but before I waste another hour or two looking for a missing wire/connector... I thought I'd ask here first.

You post this in multiple forums?  I'm pretty sure I replied to the same question over at the Suzuki-forums.

Anyway - check Ack's FAQ for Samurai wiring diagrams - going from memort both the gauges and the idiot lights get +12V power from the ignition fuse and ground through the sender, so the problem could be as simple as one power feed wire, or a whole bunch of missing signal wires.

Yes I did... (got to cover my bases).  I'll check the FAQ asap, as I believe it's as simple as a 12V power lead.

After going over some of the wiring diagrams, it seems I'm at a loss...

However, I found this... and am looking further for the 7V lead;

However, my high-beam indicator isn't working either.  But the blinker arrows illuminate... and the cluster illumination comes on, yet the idiot lights aren't when the key is turned on.  ??? ???

Check over in the Suzuki forums - I've posted some specifics for you to check there.
