At night, the backlights for the tach and speedometer will intermittently turn on and off- many times triggered by me using the turn signal.

I take it this is the rheostat on the signal stalk? Can I bypass the resistor and hotwire it so the illumination is always full bright?

Or is there an easier solution? Is the stalk (or rheostat) an easy thing to change?

If the hotwire idea is the right one, anybody know what the correct wires are?

i wouldnt hot wire them. If i rember correctly the rheostate goes to a light controller. The controller is what controls the lights (i may be wrong).

I can't answer your question, but I have a hint for replacing that turn signal stalk and its wiring. Most assemblies have the wiring snake down through the steering column to the main harness where they disconnect. If you get to this stage, tie a string or wire to the connector BEFORE you pull the turn signal stalk and its wiring through the column. That way you can simply tie the string to the connector of the new assembly and pull it easily back down through the steering column into place. It is a nightmare otherwise. Good Luck!
