I can let him have the whole underhood harness if that's what he wants but it looks like he has that I was going to follow it back to the block and just remove it from the block then he could take his old one out and plug it in its place

Here's what you're working with. Do you have delay (pulse) wipers or low/high? If your wiper switch on the column shows a delay feature, you have RPO "CD4". If the SPID sticker is still on the trunklid, that RPO should show up on there. If you don't have it, obviously you don't have delay wipers. It will make a difference on which cover you need. The screws holding it on are small torx screw heads IIRC. You'll still need a washer pump too, might as well do it all if you're going this far. You'll also need to get some bushings and bolts to mount the wiper to the mount, maybe snag those from a junker. Any G-body wiper motor would do, doesn't have to be from a car just like yours. And a nut that fits the stem for the crank arm to mount it to the motor. Thank goodness they didn't rip out the wiper arm assemblies. If you find a G-body with the same type of wiper system you have, snag the cover and all that, take the bolts and rubber bushings and the nut.

If you want new bushings, aftermarket supplies them. Search around or ask at the local parts stores.

Is the ohm rating for the original wiper switch correct for the motor? Figured I'd ask due to the change with electronics between the years for product "improvement".

Is there a second two pin connector on the bottom cap of the motor? Figure 5 on 69hurstolds's diagram.

Your purple wire is for high speed, it goes into one of the two pins on the motor connector. The yellow wire jumpers from the 4 pin connector to the other pin on the 2 pin connector.

The green and gray wire look correct as wired. Unsure on the pink wire, but it is just for the washer pump, and should run without it.

Try that and see if it will run.
