Master Window switch Needed for 1973 Olds Delta 88
Hello I am looking for a Master power window switch for my 1973 Oldsmobile Delta 88. a couple of my wires were broken when my door panel was removed for a paint job. Or can the wiring be replaced? if so what do I look for, thanks. for any all suggestions.

From the pics in the other thread, looks like wires may be frayed or broken at the switch wiring block.
Easiest repair is find another block with good wiring and splice it into the harness in place of the damaged one.
If you can't find one (it's common to most 70s GM vehicles with window switch on the door panel) it can be repaired.
You have to pry the two pieces of the wiring block apart. You will then see a bunch of J or "saxophone" shaped wiring terminals. The pins on the PW switch mate to these.
Before complete disassembly note where each wire goes in the switch block. Phone camera is great for this.
From there, it's a matter of repairing broken wires and terminals and reassembling the wiring block. The J terminals should be available. Joe P can help with a source.
Friend and I made this repair on a 1964 Pontiac Grand Prix years ago, and I did it on a 1973 Delta 88, so GM has used those J terminals for many years. I think he got them at the GM dealer.
