Main Control-Valve Body
Removal
1. If equipped, turn the air suspension switch OFF.
2. Disconnect battery ground cable.
3. Raise and support the vehicle; refer to Section 100-02.
4. Drain Transmission Fluid and remove the transmission fluid pan and filter; refer to Transmission Fluid Drain and Refill in this section.
5. CAUTION: Do not pull on the plastic lead frame. This may cause damage to the connector ends. Carefully pry up on the locking tabs to disconnect the sensors.
Disconnect the molded lead frame from the sensors.
Disconnect the molded lead frame from the sensors.
1. Disconnect the shift solenoid SSA/SS1 and SSB/SS2.

P1747- Electronic Pressure Control Solenoid - Short circuit. This is a transmission code. I suggest you seek professional help.
The overdrive light to flash on 2005 Ford Expedition is caused by either the sensor problem or the electronic pressure control problem for the tranny.
P1747 is the Transmission Electronic Pressure Control Solenoid Short Circuit. Can be in the wiring or internally.
my directional lights and speedometer do not work could this be control mudule?

current amplifier
An inrush current preventing circuit includes a rectification circuit, a temperature-sensitive component, a controller, a switching circuit, and a tank circuit. The controller outputs a control signal to turn on the switching circuit in response to the tank circuit being at a substantially full voltage, and the rectification circuit and the switching circuit forming a current loop for providing power from the rectification circuit to an electronic device. The controller outputs no control signal to turn off the switching circuit in response to the tank circuit being undercharged, and the rectification circuit and temperature-sensitive component forming a current loop for providing power from the rectification circuit to the electronic device for protecting the electronic device. the rectification circuit and the switching circuit forming a current loop to provide power from the rectification circuit to the electronic device;wherein the controller does not output a control signal to turn off the switching circuit in response to the tank circuit being undercharged, the rectification circuit and temperature-sensitive component forming a current loop to provide power from the rectification circuit to the electronic device such that an excess amount of current is prevented from flowing to the electronic device

A basic manual operating switch is able to open or close a circuit. There are electronic components that will also control the working of a circuit.
Control board
A rope is not used in any electronic circuit, because it is made of insulating material that is very hard to control and characterize.
