How do you rewire a 1986 Toyota Celica derby car to bypass the computer and other irrelevant units?

Note: Rewiring a car to bypass the computer is a complex task that should be performed by someone who is experienced with electrical systems. Attempting this without the proper knowledge can lead to serious damage to your car. The following instructions are provided for informational purposes only and should not be considered a substitute for professional help.

Step 1: Identify Your Relays

Your Toyota Celica has several relays that control different functions, such as the fuel pump, ignition system, and turn signals. You will need to identify these relays and label them so that you know what each one does.

Step 2: Remove the ECU (Engine Control Unit)

The ECU is the main computer that controls the engine and other systems in your car. It is located under the passenger side dashboard. You will need to remove the ECU by disconnecting the electrical connectors and removing the mounting bolts.

Step 3: Rewire the Ignition System

The ignition system is one of the most important systems to rewire. You will need to connect the power wire from the battery to the ignition switch, and then to the coil. You will also need to connect the ground wire from the battery to the engine block.

Step 4: Rewire the Fuel System

The fuel system is another important system to rewire. You will need to connect the power wire from the battery to the fuel pump, and then to the fuel injector. You will also need to connect the ground wire from the battery to the fuel tank.

Step 5: Rewire the Electrical System

The electrical system includes all of the lights, turn signals, and other electrical components in your car. You will need to connect the power wire from the battery to the fuse box, and then to each individual component. You will also need to connect the ground wire from the battery to the chassis of the car.

Step 6: Test the Wiring

Once you have finished rewiring your car, you will need to test the wiring to make sure that everything is working properly. Start by turning on the ignition and making sure that the engine starts. Then, test each of the electrical components to make sure that they are working.

Step 7: Reinstall the ECU

If everything is working properly, you can reinstall the ECU. Be sure to reconnect all of the electrical connectors and mounting bolts.
