Hooking Up Dash Temp Gauge

[Porscheman912]

I had to replace my gauges, or I could have gotten them repaired, butanyways, I bought some others. The far left gauge, has the temp gauge in it, and I am trying to find out if the is a wire in the harness, or if I have to run a wire to hook it up? What sending unit do I need? Any help would be great. The wiring diagram I have does not even show this gauge.

I forgot to add, this is a 75, and there were cut wires with the gauges. I know the power wire runs from fuel gauge, but there is a green wire with black dots on it. The gauges were also out of a 75.

The green with black dots sounds like an addition. The stock wire is green with a black stripe, so someone was likely trying to do the right thing and use a green/black wire.

The stock wire should connect right around the gear shift lever on the center tunnel, then go back to the temp sender on the engine.
