This adds an intermittent sweep wiper circuit to your car.  The connections shown are for a single speed wiper circuit.  This is a little more complicated than most of the other circuits (which use a transistor, relay and a few resistors and capacitors) but I wanted to use the 555 timers I had for something.  The circuit board is not one of my better efforts but you can see what it looks like here.


The circuit board and controls reside in a small console I made beneath my under-dash air conditioner.  I also made a jumper plug that mates with P1 just in case my wiper circuit fails and I need to use the wipers.  That connector connects the green and yellow wires together (restores the Org/Blk factory harness continuity).
