Ok, so here is the final result of my day. I have decided to use all 3 positions of the factory wiper switch.

position 2 = wipers low

Position 3 = wipers high

intermittent position 1 = returns wipers to park

This way I can have all factory connections with no additional relays and I use all 3 positions of the wiper switch.

wiring is straight forward. 53a is now connected to the 12v out from the wiper switch to be energized with the position 1. So if I use the wipers, I just need to put the switch in position 1 (intermittent) until the wipers park, then I can leave it there or turn the wipers off.
