WIRING
First locate your tachometer connector in the factory wiring harness that were unplugged from the original tach
gauge. The wires needed for the Dakota Digital tachometer should all be found here. The factory connector can be
cut off or the new wires can be spliced into the harness. Not all wires may be present on all years or models.
Clock Memory connection
You will need to locate a fused, co12V battery power wire for the orange, clock memory wire. The
long, orange, clock memory wire is located on the tachometer gauge plug. Check your service manual or use a
voltmeter or test light to find and verify a constant power location. One common location to pick up the constant power
is pin #10 on the radio. This should be a Red w/Orange wire that is fused to the battery.
Night dimming
The BLUE wire in the MCL-30K-TCH harness controls can be connected to other Dakota Digital MCL-3k or
MCL-30K gauges. The tachometer will automatically dim the other gauges when it gets dark (the tachometer has a
sensor that activates the dimming feature when ambient light is low).
