Wiper park wire

[noneofyourbusiness]

I am looking for the wire that tells the wiper motor to park when turned off or when using a delay module. I have included a snip from the wiring diagram for reference.

Based on the diagram I am guessing that the blue wire that goes to pin/position 3 at the switch is the park wire? I am basing this on where the optional factory delay is breaking the same wire. Can anyone confirm this?

Thanks!

Power +12VDC arrives from the BLUE/red wire.  The BLUE wire is the slow speed grounding wire. BLUE/white wire is high speed, which also gets grounded to complete the circuit and enable the motor.  The BLUE/yellow wire enables the park action by latching to ground.  Observe on the diagram the small relay drawn in the wiper motor.

BTW, there was no 'factory' delay unit for the 510, but any generic aftermarket unit would work by 'intercepting' the BLUE wire.

Thanks Paolo! 

I knew there wasn't a factory one. There was one for 620's though.  Apparently I was thinking about both vehicles while posting.  :P

Errata: I wrote 'small relay' when it should have been 'switch'.  This is the wiper transmission internal park-switch which opens circuit to ground and stops power when parked.  Here is wiper circuit 'extract' from one of my diagrams that should help reveal the workings...
