1970 wiper motor

[Forssling]

Hi All, I'm working on a retrofit of the notorious wiper motor/double relay setup on my -71 911. (probably early since it has the 70 SL35 wiring) When I've sorted it all out I can share it.

But first I need to know:
Does the motor get damaged by having closed circuits to connector 53 (slow) and 53b (fast) on the motor at the same time.

This has to do with the park circuit which always is on 53, and when I'm on 53b it will get current to 53 as well.

I can solve this with a relay, but do I have to? Is the motor using the 53 circuit as well as the 53b when on fast I don't need to.

Thanks for any input,
