Custom wiper switch?

[morbidgoat]

I am updating my wire harness and making a new gauge cluster with all new gauges and using rocker style switches to replace the original switches. I've got everything figured out except the 2 speed wiper. The switch I have is an on-off-on switch. Does anyone have experience with wiring something like this and still have the park feature work? A combination of relays perhaps?

Was doing some thinking after I posted this. I think i can accomplish this through a series 6 different relays. Wish I could do it with fewer relays, I'm sure its possible but I am not familiar with whats out there.

Just want to verify

Switch in high position should be 12v to brown

Low position should connect green to ground, and brown and red to 12v +

Switch in off position should connect green to brown/ connect red to ground/ and blue to 12v

Watching. If you are successful please post your results. Its confounding how complicated the wiper wiring can be.

Not the best but I tried to make it colored to be easier to understand

Wow that is a bunch of relays.

6 total 2 5wire and 4 4wire relays. That is the only way I could figure out how to make a on-off-on rocker switch work. You could use 2 8wire relays instead of the 4 4wire relays but the cost is about 4x more that way.

For those who are waiting to see if the relay combo works we will have to wait until next weekend. My 4 wire relays haven' shown up yet.

Final result..... needed to add another relay. Also the after market 2 speed wiper I got from classic industries needed to be wired slightly different. I had to switch brown and red in order for both low and high to work. Also the factory ran a resistor for the brown wire which is supposed to be the high speed I have mine hooked up without a resistor but dont know what long term affect that may cause especially considering this is an aftermarket motor. (Maybe don' need resistor)
