If all else fails, you should be able to figure it out with
With the power turned off, measure the resistance to chassis ground for all five wires. Two should be open, one might be open or have a fairly high resistance, one might be open or have an even higher resistance, and one should be pretty much shorted to ground. It wouldn't surprise me if this wire was black.
Now turn the power on, and measure the voltage of each wire to chassis ground. The Ground wire shoud be 0V, two others should be 0V, one should have 24VDC or something like that, and the other might have something between 0VDC and 24VDC.
I'll assume that only one measures 24VDC. That's your 24VDC wire.
Now you have three wires to identify. Play a record, and read the voltage on each of the three wires. One of them probably has a voltage on it now. Watch your meter as you press the manual reject button on the machine. It should drop to 0V.
This is your Reject or Cancel wire. I'm guessing that the Cancel switch shorts it to ground in order to Reject the current record.
The other two wires are for the Volume Control Motor. With the machine off, there should be some resistance measured between these two, but not to anything else.
Now you need to figure out the wiring in the control. Two wires need to connect to the Cancel switch. These would be Ground and Cancel.
Four wires need to go to the Volume Control Switch. Looking at the back of the switch, you should see six terminals. The four at the ends are cross-connected in an X pattern. One wire comes off of each of the wires in the X. One of these wires goes to one side of the Volume Control motor, and the other goes to the other side of the motor.
Now you have two wires that go to the inner two contacts on the switch. One of these is Ground, and one is +VDC. One may connect over to the Cancel switch Ground contact. If so, that's the Ground wire. The other one is +VDC.
As others have said, get a service manual. Your machine needs regular maintenance to keep running, or you might have big problems down the line. Victory Glass has a minimum order, but Always Jukin' doesn't.

p.s. There's a chance that Rock-Ola does things differently, and the Cancel switch has to be connected to +VDC to operate. Logic and a VOM should help you figure this out while you wait for your service manual to arrive.
