wiring on the digital clock's connector

[amilo123]

Does anyone know what should be the plus and the minus on the 3 wires on the connector for the digital clock?

I have absolutely no idea for my part.

Did you try with a multimeter? It is the best solution I guess

I did and that's what i don't get, it seams two of them are plus and the other is minus. It's logical up until now. But I thought one of them should be connected to the light, and when I turn the light on there should be current. Right now there is always power to both pluses

The problem is that there is no back light on the clock. The clock works well, but no light. From what I remember there should be a light, right? (I haven't had my clock connected for years and I am not sure)

You have a 4 way connector.

Pin 4:

Ah! There is two models i guess, mine doesn't have a back light. Maybe it is possible to mix them?

problem solved, it does have a backlight, but i didn't know that it comes on on the second position of the ignition key.
