Please note that the Mighty Wiper cannot be controlled by any General Motors column-mounted wiper switches!

This is due to the fact that GM switches control the wiper motor via the ground wire and our system must be controlled by switching the positive wire as per the wiring diagram shown below.

When wiring two Mighty Wipers to one switch using this wiring diagram please note that the wipers will not necessarily wipe in sync but both wipers will park correctly when the switch is turned off.


We're not around right now. But you can send us an email and we'll get back to you, asap.
