These relay's act as electronic switches that are controlled by the computer or by a manual switch. Once engaged the relay connects a circuit which activates a particular device.

Many vehicles will go through their entire service life without any issues related to the wiring harness or its connections. But it is not unusual when diagnosing a problem with a vehicle system to eventually locate the root cause at a damaged wire, terminal, or connector.

If you are having a problem with an electrical component in your vehicle the first place to start is in the fuse box. Most cars have a few different fuse boxes. Most of the time, one is in the engine bay and a second is in the vehicle somewhere under the dash or on a kick panel. The engine bay fuse box usually holds the larger fuses for things like the alternator, electric fans or starter. The fuse panel inside usually houses the smaller fuses for things like the brake lights, clock and radio. There will be a diagram of which fuse goes to what on the underside of the cover or in your owner’s manual. Find the fuse for the component you are having problems with and pull it out. If the glass or plastic appears dark or burnt the fuses is probably blow and should be replaced.

The other major issue within a car electrical system is that not all components tolerate the same amount of current strength or amperage. Therefore, the system must include voltage regulators and fuses to moderate flow and protect components that cannot handle the amperage supplied by the alternator. Fuses protect circuits when placed in front of the load (component). If a voltage spike causes too much amperage sent to the headlights, a fuse designed to “blow” at 15 amps will do so, preventing the current from continuing on to cook the headlight itself.

Remember always that the factory used as little wire as possible, so look at the schematic diagram to see where multiple connections are made. Remember also that your friendly electron travels through several devices on its way to doing its work so you need to systematically trace the path.

You may be lucky and just have a loose wire and banging just right on something might get it to fall back into place, but most times electrical problems are not that simple. Vehicles built in the 60s and 70s had very few electrically controlled devices as most things were controlled through a mechanical linkage. In the 80s and early 90s many automobile manufacturers started using vacuum controlled solenoids to operate small things like switches in the engine or the vents on your ventilation system. Since then, just about everything has become electronically controlled and regulated. Most of the electronics in your vehicle will last a very long time and never be changed, but when something does go wrong it can be difficult to pinpoint the problem.

A vehicle's stereo system sometimes has a separate amplifier, and when installing a new receiver, you generally need to connect the new stereo's speaker wires to the factory amp's output section. These amp bypass harnesses allow you to use the power from the new car stereo to drive your speakers and not rely on factory power.
By Hadrien Gratien. Engine Wiring. Published at Sunday, February 25th 2018, 14:13:35 PM. The engine harness is typically a large bundle of individual wires protected by a shell of insulation and conduit which helps to protect it from the elements. It is often asymmetrical, with the large end close to the fuse box and becoming smaller as it branches out over the engine. Since the various automobile manufacturers have different engine designs which also change over time, engine wiring harnesses are often unique to the year, make and model of a vehicle. Because of its proximity to the engine as well as contaminants on the road, engine wiring harnesses can degrade and require repair or replacement.

It would be easy to breeze through the removal steps and forget them. But don’t rush! You’ll want to make sure you remember the sequence of these steps, since you’ll be reversing this process to install a new stereo.
