V48Y motor wiring question

[OL'GRUNT]

I am in the process of installing a new digital controller on my old Mr. Spa. I've hit a wall in trying to decypher the wiring instructions on my main pump. It's a 110 volt, 2 speed Magnetek type SP. I'd never looked into the motor wiring, assuming it would have the expected connections for high, low, neutral, and ground, and that I would simply plug in the supplied power cord for the new controller and that would be it. Not so lucky. I've attached a scan of the wiring diagram from the motor for reference. So now I have three questions:
1. If this motor can be configured to accept the high and low outputs of the new controller, where do I put the red (low) wire, and what other jumper changes do I make? On this motor is is obvious that black (line) and white (neutral) will always go to 1 and 6 respectively.
2. If the motor cannot be configured to accept the red (low) output of the new controller it's not a problem to run with high speed only. (I have a circulator pump to service the heater and filter) If that's the case, I assume the left side jumper settings (w/o air switch) would be the configuration.
3. If possible, I'd like to understand how this motor was capable of two speeds with the old analog controller.

Thanks very much

I'd need the wiring diagram of the motor controller. the YEL/BLK goes to L1, WHT goes to L2, BLU & YELLOW is one speed, RED & YELLOW is the other speed.

Old controller is tucked away in the attic, so not easy to retrieve it to look at wiring diagram. I've reviewed the info on the the motor plate, and reserach reveals it is a single speed motor. Since the original cord had only black, white, and green conductors, I assume the controller must have had a transformer in it to give the second speed...????
I'm a bit confused by your response that I can make these connections: the YEL/BLK goes to L1, WHT goes to L2, BLU & YELLOW is one speed, RED & YELLOW is the other speed. Would that not require a switch of some sort to "share" the yellow? Sorry to be so dense, perhaps you're saying that the motor can be configured for either low or high speed? If that's the case, I'll leave the motor jumpers in the "no air switch" configuration, tie-back the red (low) conductor of the power cord, and run with high speed only...

By the way, I've uploaded a more complete copy of the motor information.

Thanks again.

don't "assume" anything until you find that controller diagram. red is usually "a" motor speed. the air switch I'm assuming cuts in the high speed winding. let me take a look at my wiring diagram for my jacuzzi. the motor just powers a pump and has an air switch.

Well, still don't have a diagram of the old controller, but I did find the owner's manual. From it I've determined that I was mistaken in my belief that the pump had two speeds. It had only one. The controller was a Len Gordon 4-postion pneumatic. That did not include a transformer, neither was there any switch to pull in a high-speed winding, had it existed. In the controller's position 2 the jet pump and the blower ran simultaneously. (what I remembered at "high") and in position 3 the jet pump ran alone. (without the whine of the blower it sounded like it was running at reduced speed.)
Additionally, I finally found a good picture of a flex-48 motor electrical connection points. As you can see, it has lugs for the 1 hot and 1 neutral of 110, and no connection point to feed a second winding.
Thanks for helping me think this thing through.

the red could go to the capacitor for start winding. the blue/yellow the other side of the capacitor.

the air switch is just that. its a air operated switch that turns on or off, the pump. a small diaphragm fastened to the tub rail has a length of vinyl tubing attached to it and goes to the motor location to a diapragm switch. pressing on the rail switch closes a momentary contact and starts the pump. another pressing of the switch opens the motor start switch. it has therefore a constant speed motor. it is a safety feature so you don't get your wet body involved with the 120 power of the pump.

I don't want to get into the wiring of the motor, but if you have a circulator pump, you don't need the two speeds on the jets pump. You only need high speed for the jets.

I'm thinking there may have been an extra wire just in case your one pump ran the jets and did the circulating.
