4.1.1 Circuit Board Connectors
On all Molex connectors, Pos. 1 (as labeled on the connector) corresponds to the oppo-
site number (as labeled on the circuit board). For example, for a 4-prong Molex, Pos. 1
on the Molex corresponds to Pos. 4 on the circuit board, and vice versa.
All position numbers given below are for the position as marked on the Molex (if a Molex
connector is used).
Molex; incline potentiometer- Pos. 1: red, Pos. 2: white, Pos. 3: black, Pos. 4: shield
