Can anybody guess what I'm about to try?

Build a waterless bidet?

"ASSY WIPER"

 

Perhaps a method to improve the original Z wipers? They certainly needed it.

Well, clearly the obvious answer would be using that module to replace the original module, but I don't think that's it. TOO obvious, even for me!   

I mean, after all... The biggest improvement you could make to the original system would be to come up with an easy way to get variable speed intermittents, but that module has a fixed 7 second delay and would be no better than what we already have.

It doesn't have to be an improvement. It just has to work. I know of at least 3 Z cars in my area that are having problems because the amplifier failed. Since the original is NLA, if I can get this to work, people will have functional wipers.

I have looked at other intermittent relays, but this will probably be the best way to work with existing wiring.

I have the wiring diagram for one of these.  It has about eight positions.  I don't know much about them except that the wiper motor must be getting a lot of amps on high speed based on how fast the blades move.. They're fast.  Actually the ancient Z motor and mechanism would probably hold you back on upgrading the system.

Are you going to design a simple harness to make it plug and play?  Looks like fun.

Yes, the plan is to make a harness go to between the factory harness and the amplifier.
