Thanks, Aye Roll (nice pun, BTW). I'll take that to mean 'they ain't no harness to hook to, and they ain't gonna be.'
Having read the board, I've already ordered the pressure sender and adapter from egauges (at least I think I ordered the right one - better check).
Looking from the back, the voltmeter is in the left position, the oil pressure is center, and turbo is right. We'll be ignoring the turbo, although I saw some people are using it as a pressure gauge. Feel free to make a suggestion, if you think it's worth the effort on that one. On to the wiring:
Left (voltmeter)
top plug (light I'm assuming)
- two brown wires
- one black wire
The brown wires
- one goes to the same location plug on the oil pressure (again light)
- one goes to the light plug on the turbo, which then sends another out to the main harness
The black wire
- goes to small plug (light) on top of the oil pressure gauge
bottom plug (voltmeter)
- two black wires
- one red/blue wire
The black wires
- one goes to the lower plug on the oil pressure, which sends another to a spade connection marked with an upside down "T". That spade sends another black wire out to the harness
- one goes to the small plug (light) on the voltmeter
The red/blue wire
- goes to another red/blue wire on the oil pressure, which goes out to the harness.
The black wires are all located in plugs which have an upside down "T" next to them. The blue/red likewise, with a "+". On the oil pressure gauge in the middle, there is a green wire which goes direct to the harness.

Whew. So, as I read this,
black = to ground
red/blue = to 12 v power (wire to fuse #1 or #13 - I've seen conflicting comments on older posts
green = to oil pressure sender
brown = splice to other instrument lights...? Can I wire this directly to a fuse?
Thanks for the patience - though I'm confident in my mechanical skills, electricity is something I don't understand. Pretty sad, actually, when I worked for an EE software co. for years.
If a picture would help, I'll post one.
Best,
Lanval
