Wiper Motor Wiring to EZ Harness

All,

 

This has been talked about many times, but still the answer still eludes me. Actually have spent the last few weeks reading endless old post on this and trying to find a way to get low and high. So, my apologies if there was a thread that breaks it down that I've missed.

 

I'm attempting to use the stock combo switch and EZ wiring harness but there is no intermittent relay. The following wires are coming straight from the motor, but which ones need what?

 

Blue w/red stripe going to a small relay on the gear housing

Blue w/white stripe that goes to a larger relay

Yellow that goes to both large and small relays

Black (that grounds to the casing)

Black that goes into the windings of the motor

Black that ALSO goes into the windings of the motor

 

Someone please break this down and help an electrical idiot out. How do I get power to the motor and two speeds? The Datsun wiring diagram doesn't explain what happens in the intermittent relay and that is where I get lost. So how does the 12 vdc get to the motor? And which wires get a ground from the combo switch to make Low and High?

 

Thanks,

Mark
