12 volt switched wire color in Cobra 25?

[JSMachine]

I'm hooking up a RF Limited TRB X2 echo board in my Cobra 25, and I am unclear on which wire is the 12 volt switched on this thing. My power switch has five wires on the back terminals. Black, green, blue, yellow, and red. I would think it is either the yellow or red, but I'm not sure which.

Thanks.

The use of a volt meter would come in handy here.

I've got one, but the radio isn't under power. Would I just check continuity between ground and one of the wires when the switch is switched on and off?

Look at the very back of the switch. there should be two wires there one is hot when plugged in and the supplies power to the radio;

Hope this helps.

Here is a picture of the back of the switch.

Without a schematic a picture does nothing.

I agree, a volt meter and 2 minutes of testing will be your best bet.

Here's a link to a schematic, but I don't see wire colors http://www.cbtricks.com/radios/cobra/25/graphics/cobra_25_om_sch.jpg

Looks like the red one and what ever is right across from it.

yep, the red one and the green one is 12v.
one is switched and one is not
work the switch on and off and watch the contacts open and close
looks to me the green one is switched
