Does anyone know what the "code" is for the wires that plug into the Proto smoke boards in a dual smoke diesel? One has four sets, in addition to the W/Y for the smoke unit fan motor, that slide onto pins; Blu/Blu, B/R, B/B, and R/B. The other has three sets: O/O, R/B, and G/G ... I think the one of these sets is for marker lights, and the other for backup headlight?
Anybody know? Thanks!
