making sense of dash cluster connector measurements

Thanks. Wasn't trying to measure resistance, just continuity. Skykeith, appreciate understanding now that some of these circuits are parallel. From what I gather , two of the cluster wires do end up back at the fuse block.
The confusion was that in the actual big manual, dk blue is supposed to be for feeding 12V to the dash, but in my case and in the pdf, black feeds it.
I bit the bullet, chopped that wire off and fed my 5V transistor from this wire, as Red fishh or 67Dart273 mentioned in another thread. Now, after 5 dash cluster removals and installations, I have gauages!! I think adding the circuit board ground also helped.
Thank you all!! This calls for a financial donation to the board.
