What do these wires go to?

[DissFigured]

In the diagram below, I do not know what wires go to letters:
C, D, and E

C - Ignition switch feed.
D - Temp gauge/idiot light
E - Oil Pressure gauge/idiot light

So are D and E just Ground wires then?If I ground them to the same place I grounded:
D - Temp gauge/idiot light
E - Oil Pressure gauge/idiot light
will that work?

and the mystery wire coming from the wiring harness says "Gauge const voltage". Is that the one that goes to C?

D and E go to fuel and Temperature guage. They should both come form the same side of the voltage constant unit. Thats that box your requesting the wires from. It keeps the voltage constant to those guages. C is usually goes to the center point on the ignition switch.

I thought I said that?

 

[mustangman1974]

yup just clarified. it seemed he wanted to ground some wires, so I clarified.

Cool............ I know how he feels. Those Factory schematics give me a headache.
