On the Porsche 914 the original windshield washer is operated by compressed air supplied from the Spare tire.
Here is the switch that replaces the original valve in the steering column. With this switch installed, an electrical washer pump can be operated with the wiper switch.
I got some requests if it would be possible to have a complete kit available. So I put together a complete kit, and also have now options. It's not yet on the website, however here is the information with the options and prices.
Option 1: Switch only - $15.00 PLUS $5 s/h
Option 2: Relay kit only - $35.00 plus $6 s/h
Option 3: Switch and relay kit - $50.00 plus $6 s/h
Option 4: Option 3 plus pump - $72.00 plus $8 s/h
The switch is pre-wired and includes the mounting plate and some washer for adjustment if needed.
The relay kit includes all wires, a fuse, and connectors, shrink tubing, bolt to mount the relay, as well the disc for the filler cap.
Here is the wire diagram which will also be included in the step by step instructions.
The switch can be ordered at http://carmagic.us/washer.html
