Hi all: I want to replace my 1972 Scout II original wiper switch with a new one. The old switch has five connectors labeled F, W, A, P and one that is not labeled. All have wiring going to them, and all wires are black, except "W" which is green. The new switch has five connectors labeled B, W, 2, 3, and 1. According to scoutparts.com, these mean: B - battery W - washer 2 - low 3 - high 1 - not used Does anyone know how to route the wiring? I can't seem to find anything on binderplanet that tells me what the old labels mean.
