Just looked on the internet & found some info on the wiper motor. I will contact these people to check on the wiring & switch.
Wiring connections to the motor
3. Wheel Boxes
The most popular wheel box size is 32 teeth on the inner drive wheel and the ideal length of shaft from the inner face to the end of the splines is 2.5 inches. This allows for the thickness of material on fibreglass cars as the first spacer can be cut down in size allowing for varying thicknesses through the bulkhead where the wheel boxes fit. There is also a 40-tooth wheel box which will reduce the amount of wiper arm travel.
If the car has a split screen then it is quite easy to fit what was called the clapped hands system. This is by turning one of the wheel boxes through 180 degrees.
5. Drive or "Bundy"Tubing Sets
It is far better to use the recommended wiper tubing from Lucas than to use copper tube as this can be noisy and wears very quickly on any bends. Wear of the drive tube causes friction that can lead to the motor burning out.
Bundy tube sets can be made up providing you give the supplier 2 dimensions. The first is the distance from the motor to the centre of the first wheel box hole, and the second the distance between the wheel box hole centres through the bulkhead. Obviously if there is a 3 wiper system then there is another dimension needed. Try to avoid sharp bends in the tubing, If you have to bend the bundy tube, an easy way to form the shape is to insert the drive rack into the tube before bending. This will keep the tube the correct diameter on any of the bends (very much like a plumber bends copper piping by inserting the spring). Always grease the rack liberally before inserting into the bundy tube.

6. Switch
It is important that you use a correct wiper 2-speed switch. The reason for this is that when the switch is in the off position with the ignition switched on there is one connection which becomes live. This operates the parking position. If you use a non-live switch then the wipers would stop whenever the switch was switched off.
LUCAS WIPER SWITCH Part No. 35927
Terminal Connections
4. 1st speed red/green light
8. Park brown/light green (linked to no.4 when switch is on off position)
6. Ignition live green
2. 2nd Speed blue/light green
The park position can be changed by reading the Lucas information leaflet. If purchasing a second hand motor make sure there are 3 wires going into the motor body. This is the way to tell if the motor is 2-speed, 1 speed only has 2 wires.
All of the above components and full assemblies cut to your cars specifications can be purchased from Stafford Vehicle Components.

I can't copy the pic portion of it, but it looks identical to mine.
