Wiring pinout for 98 Mustang defrost switch

[JadeFalcon]

Installed a 03 Dash in a 98 cobra, and just finishing up the accessories....

I cannot find the wiring diagram for a 98 cobra defroster to save my life... I
even have a chilton's and it dosent go into the pinout, only which are the illumination wires.

The harness has 5 wires.. which is puzzling to me, I can understand the positive which the switch opens and closes to the rear defrost, but then there should only be 2 additional wires to work the illumination.. thats where I'm lost.. theres a 5th wire I have no idea what it does, so I need to see a diagram... Now, when I hook the switch to the positive lead and the out side, it sticks the LED on..which again.. makes no sense.. I spent about 45 min with it and couldnt figure it out.
