I have been trying to get rid of the single speed wiper switch for a while now and convert it to an illuminated locking push button affair. This will match all my other buttons in the dash but will work for any simple on/off switch.
You will require a couple of relays to do the job one of them 4 pin and the other 5 pin. This is because of the 'park' trickery involved when switching off the wipers at any point and they continue working until coming to rest at their usual spot.
Looking at the back of your original switch you should have two green wires joined at a spade connector, a single red/green and a single red/brown. If you also have a blue/green wire then that is for the fast speed and will become redundant for a single on/off switch.
Take a fused 12v+ feed from your ignition. This need only be a thin gauge wire as it wont be taking large amounts of juice and will only be used for operating the relays that take milliamps to open and close the circuitry.
This feed needs to go to your chosen switch, again the switch is only controlling milliamps so can be of any size. From your switch take a second wire to your conveniently placed relays.
This wire from your switch goes to 86 on your 5 pin relay and is earthed via 85.
The original double green wire that supplied 12v+ to the old switch goes to 30.
Make two short jumper wires.
One will have to join the red/green wire at 87 on the 5 pin relay and go to 87 on the 4 pin relay. The other from 87a (the center pin in the 5 pin relay) to 86 on the 4 pin relay. Again this second jumper wire is earthed via 85 on the 4 pin relay.
The final green/brown wire from your original switch wiring goes to 30 on the 4 pin relay.
..........and thats it. Your wipers will work at the press of a 99p button. Or owt else you can scavenge.
Dont worry about the block 1 to 5 in the picture, thats the connections at the wiper motor. Now then, who wants to do one with a twin speed jobbie.
