Clock came this morning, 3 day delivery, not bad.
Clock has 4 wires
Black - Ground
Red - Switched Positive
Yellow - Continuous Positive
Orange - Dimmer
Clock will not work unless yellow is connected and to set clock, set button is on the back. Instructions say it is 12/24 hours however have not found the 24 hour setting (yet)
I connected the ground to existing ground from old Gauge and connected the red and orange to existing connection for old gauge light. Since I needed continuous power for the clock I ran a yellow from the Battery and connected the Volt Meter to the same wire as the clock.
Sort video of the clock cycle.
