I can check and verify with the wiring diagram, but just looking at what you have so far,
Ammeter Blk=grnd Blk/Wt = pos
Fuel Tan= grnd(actually, the tan wire will be the one coming from the tank sender unit, which is basically a ground thru a resistor) Pink = pos
Temp gauge Pnk = pos blk = grnd grn is from sender unit
Oil press Pnk = pos blu = grnd(from sender unit)
Not a clue on the clock...I'll have to check the diagrams...
