Electric washer with wipers activation, Nice additions to SirAndy's tutorial - now with PICTURES Options

[Valy]

I've been struggling with my washer for a long time. I liked the idea of electric washer but had the simple wiper switch that doesn't have the additional contact for the intermittent position and can't stand the idea to drill a hole for the button in my nice dash.
I'm also a CSOB (aren't we all?) so won't buy the $100 new wiper switch.

For those in need, here is the link to Andy's tutorial.

I started from there but wanted to make my wiper switch trigger it and start the wipers at the same time (IMG:style_emoticons/default/smile.gif)

How do I do it simple, "original" and cheap?
Here it comes:

First, I need to trigger the wipers when the washer pump works.
You don't need the intermittent relay to trigger the wipers when you trigger the pump. In fact, the original intermittent relay combined with the washer pump like Andy suggested may cause some unwanted electrical gremlin due to the switch wiring. So, if you're like me and only want the wipers to trigger once when you activate the pump, all you need is a regular relay! ($2 on ebay with the socket and wires)
Here is the schematics of the modified circuit that I used:

I used the Brown/Black wire that was existent in my car to trigger the relay and the washer pump.

I also modified the wiper switch and added the missing "53c" contact. It's a pretty simple modification but don't have the pictures right now to show as the switch is already on the car.
I'll add the pictures if there is enough interest in this thread.

It's all plug and play except the new wire (A) that needs to be connected to the pump. That's it. Yes, it's simpler than adding an external switch (IMG:style_emoticons/default/wink.gif)

Oh oh....
Well I got the switch and installed it but no love.
One of the big reasons I got the switch was not only to get power for a pump I installed but also to hopefully correct what I thought was a bad wiper switch as my wipers stopped working completely (although I never did have a high side function)
Anyway, I hooked up the 924 switch and no love. No doubt caused by pin 53a at the wiper being zero ohm. And oh yes it blows the fuse at slot 8!
But the really odd thing is this....when I removed the rd/blk wire from the wiper that connects 53a, the low side of my wiper starts working when the 924 stalk switch is in the off position with all the other positions non-functional. The self parking doesn't work either. It begs the question about the switch being plug and play? Is it truly or when doing the install are any of the wires on the 924 switch supposed to be re-routed down the plastic router at the switch? And of course compounding the problem is the unknown year of the motor and how that could effect the routing of the wires on install.
No doubt the wiper motor is bad as zero ohm at 53a isn't gonna work at all, but odd that I'm getting functionaility when 53a is unhooked.
I wonder which pin does what? That could be useful in trouble shooting....
Grrrr.
