Using a 924 wiper switch, that has 2 extra wires, it has the ability to support a power washer pump. As you can see i cannot use a non inflated spacesavertire to pressureize my tank....

so this is how it worked out.

need 1 924 wiper switch (77-79 ONLY)
need a VDO washer pump (common on Audi, porsche, volkswagens, and Volvos)
i paid about 10 bucks each for the pump and harness shipped from ebay.....

switches are alot more.....
