The procedure mentioned in the service manual is correct for 55 cars IF the compensator switch is completely original and terminals and markings are still visible. However, 55 switches were problematic in that the screw terminals would corrode if exposed to excessive moisture. Because there was almost always a constant 12 volts feeding the switch the corrosion could also cause shorts to develop requiring the switch to be replaced. Attempts were made to alleviate this problem by applying various water proofing compounds which would cover terminals and markings. On original 55 switches, if terminals or markings are covered the A terminal has a yellow wire and B terminal is pink.

For 56 the switch was revised so that different style terminals are inside a weatherproof enclosure on the switch bottom. To access those terminals a cover held by 4 screws needs to be removed. While solenoid placement and limit switch type were also revised for 56 the procedure for raising or lowering at the control sw is still the same but you need to access the terminals differently and wire colors may be different. The terminals are not labeled A or B and only designation is by a dot of color to match wire loom..

Because of the issues with the 55 switch, when stock ran out and a 55 control switch needed changing it was to be replaced by the 56 version. A small pigtail with different color wires was spliced to the 55 loom to connect to the new style terminals. If your car has had that change refer to the service article on page 22 in Counselor Vol 30 #6. In some instances the pigtail was not used and the different style terminals were added to the original looms instead of the pigtail.

Dealers also had their own way of doing things and the factory suggested waterproofing fixes or switch replacement method may not have been precisely followed even if they used the suggested parts. Over the years any number of other methods or changes in wire colors could have been done by independent mechanics or owners.
