FAQ
What is a wiring harness?
A wiring harness is a collection of wires that are bundled together and run through the vehicle. The wiring harness connects different components and allows electricity to flow between them.
What is an engine control module?
An engine control module (ECM) is a computer that controls the engine’s performance. The ECM receives information from sensors in the engine and makes adjustments to optimize performance.
What is a transmission control module?
A transmission control module (TCM) is a computer that controls the transmission’s performance. The TCM receives information from sensors in the transmission and makes adjustments to optimize performance.
What is a fuse?
A fuse is a protective device that is designed to break the circuit if a short circuit or overload occurs. The fuse protects the electrical system from damage.
What is a ground?
A ground is a connection to the earth, which allows electricity to flow back to the source. Ground connections are important for the electrical system to function properly.
What is an on/off switch?
