I have a Lucas wiper switch. The number of the switch is 39125. It has four terminals. My intent is to use this switch in place of the toggle that comes with the kit. As I understand it, this is the same switch that was used on the Superformance cars. The terminals are numbered 1, 2, 3, 4. See the pictures below. So I have two questions.....at least.

How would I go about wiring the switch to work with the wiper motor that is included with the kit?

Second question. In addition to rotating two positions, I assume "high" and "low," the shaft of the switch actually pulls out of the housing about an inch or so (see the picture below). What is the purpose of the shaft pulling out from the switch?

Thanks for the help.

Joel
