"When an electric solenoid engages it can produce an electromagnetic surge of current. Diodes are used to protect the vehicle's computer from back voltages. Ford originally placed the diodes on the circuit board of the 1989-94 solenoid pack. In 1995 they moved the diodes from the circuit board to the vehicle harness. We use the same board for all E4OD solenoid packs. This means there will be diodes on both early and late solenoid packs. There is no need to have diodes on the circuit board for late style solenoid packs however they will not cause any problems. These diodes have next to nothing for resistance in forward current flow. Two diodes in line as opposed to one are not noticed at all by the computer. Think of it as double protection..."
