Unless the vacuum leaking and hissing thru that open port is extremely high and the vacuum source is very low the small hoses should not have anything to do with the wipers moving or not. If the motor is not working you may need to look elsewhere for that problem.

All the small hoses do is activate a piston inside the motor to change position of a part that determines the sweep range. With the lever in one position the wipers do a full arc and in the other, a faster motion because of reduced travel but a smaller area directly in front of the driver is all that is wiped. Advertising claimed that reduced arc speed up feature was for use in heavy downpours and I suppose they might have a point because the action is quite fast compared to the regular high speed.

Yes EXCEPT they are not the same length on the motor end. Just remove the knob (same as all) then the lever (don't lose the spring or special washer) and you will see a panel nut for a 5/8" socket. Unscrew and drop the switch, then swap the hoses. Takes like 2 minutes.

That's possible, but virtually all the V8 cars use a whip there not a jumper. So this one (rear running lights) should be available.

Though Kevin I believe that you are supposed to attach it to the ACC terminal on the starter switch. Only logical place if they gave you a ring terminal.

To answer your question here, this is off a factory schematic of the push button system, and then the mating connector as shown on the factory wiring harness. There are no revision notes to indicate its prior absence, but the dwg itself is only from Armistice Day of 1955. I suspect they were shipping 56's before that point. I suspect the headlight switch connector would have been the place before then.

Another clue comes that the manual transmission 56 senior harness (yes really) was drawn up June 23rd; obviously it's missing the Push Button stuff but it's curiously also missing the hand brake light circuit. I would have assumed the manual cars would have had it from the factory, but apparently not.

That pod light power has always been a question so glad to see the preferred inline connector is documented. Wonder if that happened when they changed the early yellow PB control power wire in the main loom coming from ballast resistor to white to eliminate the confusion with the yellow wire from the park button. Around that same time must have been when they also changed the PB actuator harness by running a separate orange power wire all the way from the fender relays to the pressure switch instead of having the pressure switch spliced in the harness to the R/W wire feeding the PBs

Interesting on the whip. I don't recall seeing that configuration -- but the memory is failing. The cars I remember had a single wire to the tail lights and a separate jumper with two connectors to the rheostat which meant both terminals were used.

On the spotlight power, I guess you could connect to the ign sw ACC terminal but the downside is the key would have to be on to use the light which I guess would not be that big a deal. Unlike Packard, I am a firm believer in fuses or breakers on all accessories so if that is the power point chosen I would hope some kind of protection would be added.
