Today I tested the idea that I could swap in older ('02) illuminated window, door lock and mirror switches into my '05:
failure... and success!... and failure... and sorta failure
The door lock switches do not work... and I can see why. The plug is a 4 wire plug, and at least on the '05 KJ, there are only 2 wires to that plug - the 2 outside wires. The 2 inside wires go directly to the LED (or the spot where the LED should be).
So now I have to see how to tap into a 12v ignition switched wire in the door. I don't know if one exists because the mirror power is on all the time (as far as I know) and the defrost is only on when the defrost relay is on. I don't know if it is possible to tap into the wire for the door lock switch itself or not, and if I do will that cause issues.
The mirror switch worked like a champ - just plugged the old one in and it now glows green as God intended.
And regarding the master front window switch... It plugged in and even illuminated all the LEDs on the older switch, but the front windows don't operate. I was afraid of this because when I looked at the circuit boards, they had obvious differences. I'll see what, if anything can be done there, but I'm guessing that will have to be a hack-job to get the light to those two back switches on that master panel.
