Understanding the Importance of a Wiring Harness

When I first started working on my vehicle’s ignition system, I quickly realized how crucial a wiring harness is. The wiring harness connects the ignition coil to the vehicle’s electrical system. A good harness ensures that the coil receives the correct voltage and current, which is essential for optimal engine performance.

Identifying Compatibility

Before purchasing a wiring harness, I always ensure it is compatible with my vehicle’s make and model. Different vehicles have varying electrical systems, so I check the specifications carefully. I find it helpful to consult my owner’s manual or look for online resources to confirm compatibility.
