When wiring up a car, or wiring in an ECU, one of the most important aspects

, is good wiring.

Now, everyone thinks of wiring as being a good 12V power supply - "I must have a good 12V. I've run really thick battery leads". It's not the only thing.

There are two sources to power supply. You've got a ground, and you've got power.

Let's take an injector for instance. That has power, and it has ground to operate it. An ECU will ground the pin of the injector to open it.

If you are wide open throttle running down the drag strip, and you have a bad ground supply to the ECU, then that will have a bad ground supply to the injector. That can lead to leaning an engine out, and even causing an engine blow up.

To ensure this doesn't happen, you need to make sure all of the ground points on your engine are in really good condition and good spots.

On and OEM factory car, they often have about 4 different ground points. They have one at the front of the engine, one at the back of the engine, they generally have one down on the side of the motor, and one that goes from the alternator bracket to the battery.

These are all critical to the way an engine runs. Whether it's to ground injectors, or ignition coils that need to be grounded to give good spark, once again, if you don't have good ground for your ignition system, you're not going to have a good spark, it's going to break down under load when the engine is trying to produce maximum power.
