Materials:
* Electrical wires (various gauges)
* Wire connectors
* Insulation tape
* Wire stripper
* Wire crimping pliers
* Multimeter
*Car wiring diagram
Tools:
* Wrench set
* Screwdrivers
* Ratchet with head
*Long Nose Pliers
Steps:
1. Battery de-energized
* Disconnect the negative cable from the battery to ensure safety.
2. Dismantling old wiring
* Locate and disconnect old electrical wires from related components.
* Take photos or make notes about the location of the wires so you don’t get confused when installing new ones.
* Remove old wires and components.
3. Installation of new components
* Install new electrical components in place.
* Connect the wires to the components according to the vehicle wiring diagram.
4. Wire connection
* Twist the ends of the wires together using a wire connector.
* Crimp the connection using wire crimping pliers.
* Make sure the connections are secure and have no exposed wires.
5. Wiring
* Route the wires along the same routes as the old wires.
*Use zip ties or electrical tape to secure the wires in place.
* Avoid kinking wires or allowing them to come into contact with hot or moving components.
6. Wire insulation
* Insulate all connections and exposed wires with insulating tape.
* Make sure the insulation is secure and does not allow moisture or dirt to enter.
7. Functionality check
*Connect the negative cable to the battery.
* Turn on the ignition system and check the operation of all electrical components.
* Use a multimeter to check the voltage and continuity in the system.
8. Final assembly
* Reassemble any removed panels or components.
* Check proper operation of all systems.
*Adjust or repair any faults as necessary.
Adviсe:
* Use the correct gauge and type of wire.
*Follow the car wiring diagram to connect the wires correctly.
* Make sure all connections are secure and insulated.
* Check fuses and relays after replacing wiring.
*If you are not confident in your electrical skills, leave this task to a professional mechanic.
