1949 'Baby' Lincoln hydraulic pump installation

Hello.  I'm new to the forum and would apprceciate help with a problem that has me stumped.

 

I have recently bought a 1949 Lincoln 9EL, the flathead V8 that was also known as the 'Baby' Lincoln, which I am restoring.  Like a number off other cars from and after that era, including the bigger and better known Cosmopolitan, the 9EL has an hydraulic pump that operates the power (hydraulic) windows, convertible roof and seat adjustment.  The pump is a 'Dura Pump', made by Hydro E-lectric.  The company still exists today, and I had my pump re-built by them this fall, so it is in full working, restored condition and is warranted.

 

So far so good, but my problem is that having initially removed my Dura Pump, I am confused about how to re-wire it now that it is back in the car.  The three hydraulic lines are in the right place, but I'm not sure about the electrical wiring, especially since some of the wires were different colors when the pump came back from the rebuild.  There are four wires, with one seemingly obvious 'hot'one that connects to the pump solenoid, but the other three can all fit the remaining three connections.  There are two on top of the Bakkelite Switch, and the other is on the side of the switch body.  You'd think trail and error would sort this out, but it hasn't.

 

At present, having filled the pump reservoir with ATF (now recommended), I can make the driver's side window go up if I turn on the ignition and manually turn the Bakkelite Switch while also pressing the window switch, but the other windows won't raise, although the solenoid in each one clicks when I press the relevent switch.  That is as far as I have got.

 

What should happen is that with the ignition on, depressing any window switch should send current to the Bakkelit Switch and make it twist to allow hydraulic fluid to flow to the piston beneath that window, but that isn't happening.

 

A wiring diagram would help, or photographs with an explanation of what I need to do or am doing wrong.  I've been in touch with Hydro E-lectric, but they don't have any diagrams.  The car has been unused for many years, and the hydraulic system had become dry - when I re-filled the reservoir and ran the pump, I assume that a lot of the fluid remained in the pipes and the working window piston, which may explain why three of the winows won't lift, but that isn't any help re. how to make the window switches activate the Bakkelite Switch. 

 

Thank you for any help and advice.
