I've got a 2 door GP with a broken window switch. I need to know which wires go to which pins. I can't find the wiring diagram or the layout of the connector. Any help?

Sure, here are the wiring diagrams for the 2-door window system and the connector view to help you get the wiring fixed up. Check out the images (below). Let us know if you need anything else.

Thank you for the diagrams! They shed a bit of light in my harness but I'm noticing mine has seven wires in total running into the connector. Would it be possible there's another version of these diagrams? I won't rule out the possibility of that the wires were messed up years ago by a shop/dealer. Again though, thank you for the diagrams, even with this I've got a better idea of what I'm doing!

Yes, this is another version of the wiring diagram for a 1995. It has 6 wires. Check out the images (below). Let us know what you find.

Thank you for all the help. I've been able to identify and label all my wires appropriately. The arrangement of mine don't match up to the arrangement of the ones on the diagrams, but I'm going to rearrange them to what the diagrams outline. Hopefully this will allow me to install my new window switch with success. Again, thank you for all the help!
