Anyone know what these wires are for?
 
They're filthy and I can't tell the colors but I'm guessing one is the fuel pump test lead with the connector ripped off and the other is the diagnostic tach lead with the connector ripped off.
 
I'll clean the wires up and take a better picture.. 2 of the wires are the same color and the other one is grey.
 
Tie the two white wires together, tape up and place inside the harness - they are a series of feed wires to your dash bar-graph tach.

Disregard the gray wire; it is an extension of the fuel pump feed and isn't necessary for a daily driver. Tape and stow in the harness.

As a footnote, if the tach doesn't work, tying these wires will fix that. However, if the tach goes full tilt, it's defective and needs repair.
