Help with wiper motor & switch

You have a mismatch on your motor/switch combo. The motor is for variable speed wipers. If it were me, I'd get the correct switch. If you just need to get the wipers to work on high for your inspection, you should be able to find a hot lead coming from the switch and connect it to the correct motor connection. Make sure the wiper motor is grounded properly where that copper strap and ground wire is in your photo. Clean the surfaces to make sure.
