OK here it is. I have 6 wires going to my dash. They are 3 together in two seperate small looms.
I have the large plug to the system check gauge hooked. These are in addition to the big plug going to it.

They are Purple- Grey- Black these have eyelets on them to be placed over a guage, I assume the tach ??? They have shrink tube on them as if they have never been used.

The others are Black- Purple- and white w/ brown or tan tracer. These are cut and no ends on them...... Do I assume right that these wires go to a trim gauge??? If so what is each wires function???
