Heres how to switch your defroster switch to the defroster switch from an 80 series or similar. You can use the conector from your 60 switch so its pretty much plug and play. I spliced in an extra wire on pins 3, 2, 1, and 4 on the 80 series side of the below image so i can daisy chain my switch backlighting together. This is kinda optional. I need to go out and test this one in the truck but on the desk with the 12v battery it all works
