Did you have to add to the length of the wires on the small harness so you could make the connection under the dash? Since you mounted the small box on the back of the gauge, seems like the wires would be to short to reach under the dash for the connection. Allso thanks for all of your help.
If you want you can "splice" into the bigger wires and just run the one down,or extend the smaller wires and run them down.I`m going to take mine apart and run the small wires down so I can hook-up a dimmer to the needles.Just a little to bright at night.
