Wiring for clock

[worzella]

I have verified the red and brown two wires on right are power/ground, but no idea what grey with red line wire on left is

 

Perhaps a light power lead?

 

Thanks!

light...?

How about a pic of the back of the clock. The terminals in the clock may be labeled and could be referenced to a diagram online. That being said, it's almost certainly the light.

No markings on back

 

And just want to be sure what it is from a user who has dealt with one before applying 12v😁

Found via search.. should have done in first place

The Grey wire is for the clock light and is dimmable just like the other dash gauges.

You might find a rubber plug on the back of your instrument pod (see attached picture).

This is the plug for the clock (red, brown, grey) and the light is tied into the existing dimmer circuit.

PS: I made my 3-pin connector out of a trimmed appliance plug. The 3 pins on the dash pod are "almost" straight.

If you have a seperate gauge pod as well, you can pick up the dimmed feed for those as well.

I was just looking for the lighting details for my oil pressure gauge.

I used the 3-tab connector under the dash for my extra gauge lights.

7(a) is the connection to use for dimmable lights (connected to the rheostat in the headlight switch).
