Materials and tools:
* Electrical wire (various sizes and colors)
*Terminal blocks
* Electrical tape
* Crimping pliers
* Stripper (tool for stripping wires)
* Set of keys and screwdrivers
* Tape measure or ruler
Steps:
1. Identifying needs
* Determine what instruments and devices will be installed in the car.
* Calculate the total current and voltage that will be consumed by these devices.
2. Selection of wires
* Select the appropriate wire gauge (size) for each device based on current draw.
* Use different colored wires for different circuits to make identification easier.
3. Wiring
* Route wires in protected areas, avoiding sharp edges or moving parts.
* Secure the wires with clamps or ties.
* Protect wires with electrical tape or PVC tubing where they may be exposed to moisture or abrasion.
4. Connections
* Connect wires using terminal blocks or twist ties.
* Strip the wires using a wire stripper and then crimp or twist the terminals.
* Check the connections and insulate them with electrical tape.
5. Grounding
* Ground all metal parts of the car body, as well as the negative terminals of the battery and devices.
*Use appropriately sized ground wires.
6. Connection to power supply
*Connect the positive terminal of the battery to the main fuse or power rail.
*Connect the negative terminal of the battery to the vehicle ground.
* Connect the wires from the devices to the power bus or main fuse.
7. Testing
* After wiring is completed, test the system by turning on various devices and checking their operation.
* Correct any connection or grounding problems.
8. Documenting the scheme
* Create a detailed diagram of the electrical system, including the location of wires, terminal blocks, and fuses.
*Keep the diagram in your car for future reference.
Safety Tips:
*Be sure to disconnect the battery before starting any wiring work.
* Use tools with insulated handles.
* Do not overload wires and fuses.
* Keep unused wires insulated.
* Check the electrical system regularly and correct any problems.
