2000 mercury cougar radio wiring diagram – What is a Wiring Diagram? A wiring diagram is a straightforward visual representation in the physical connections and physical layout of an electrical system or circuit. It shows how a electrical wires are interconnected and will also show where fixtures and components may be attached to the system.
When and How to Use a Wiring Diagram
Use wiring diagrams to assistance with building or manufacturing the circuit or computer. They are also helpful for making repairs. DIY enthusiasts use wiring diagrams but they’re also common in home based building and auto repair.For example, a house builder will want to confirm the place of business of electrical outlets and light fixtures by using a wiring diagram in order to avoid costly mistakes and building code violations.

Essential Tips for Safe Electrical Repairs
Repairing electrical wiring, a lot more than any other household project is all about safety. Install an outlet properly and it is as safe as it can be; do the installation improperly and it’s really potentially deadly. That’s why there are so many rules surrounding electrical wiring and installations. The rules may be complicated, for sure, and sometimes confusing, even for master electricians, but you can find basic concepts and practices that sign up for almost every electrical wiring project, specially the kind that DIYers are allowed to tackle.
Here’s a review of five of the biggest rules that will assist help keep you safe when making electrical repairs.
1. Test for Power
The easiest way to prevent electrical shock is to ALWAYS test wires and devices for power before implementing them or near them. Simply shutting from the power is detrimental enough.
Further, it isn’t uncommon for circuit breaker boxes to be mislabeled, specifically if the electrical service has been extended or adapted in the past. The circuit breaker label might not exactly accurately describe just what the circuit breaker actually controls.
Always test for power before working on any circuit wires.
2. Check Amperage Ratings
All electrical wiring and devices provide an amperage, or amp, rating. This is the maximum level of electrical current they are able to safely carry. Most standard household circuits are rated for 15 amps or 20 amps, while large-appliance circuits (including for electric dryers and ranges) may be rated for 30, 40, 50 amps, or even more.
When installing or replacing wiring or devices, each of the parts you have will need to have the appropriate amperage rating to the circuit. For example, a 20-amp circuit will need to have 12-gauge wiring, which is rated for 20 amps. If you install 14-gauge, 15-amp wiring on that circuit, you create a fire hazard as the 20-amp circuit breaker protecting that circuit probably won’t shut off prior to the 15-amp wiring overheats.
When replacing a switch, fitting, or outlet receptacle, make sure to not use a device that is rated for additional amperage as opposed to circuit carries. This is especially important when replacing receptacles. A receptacle rated for 20-amps has a unique prong shape through which one of the vertical slots has a T shape. This shape allows 20-amp appliances, which have a matching T-shaped prong, being inserted. Installing this type of receptacle over a 15-amp circuit makes it possible to possibly overload the circuit in the event you plug this kind of 20-amp appliance involved with it.
Note, however, that there is absolutely no danger to installing 15-amp receptacles in 20-amp circuits as it is perfectly fine each time a plug-in device draws less power compared to circuit amperage. In fact, it is quite normal for 20-amp general-use circuits to get wired with 15-amp receptacles.
3. Make Tight Wiring Connections
Electricity travels along conductors, like wires along with the metal contacts of outlets and sockets. Tight connections between conductors create smooth transitions from one conductor to another. But loose connections behave like speed bumps, restricting the flow and creating friction as well as heat. Very loose connections can bring about arcing, through which electricity jumps over the air in one conductor to a new, creating tremendous heat.
Prevent fire hazards start by making sure all wiring connections are tight and also have full contact of the conductors being joined. When splicing wires together, only use approved wire connectors (“wire nuts”).
Outlet receptacles and switches in many cases are manufactured with push-fit wire connection slots around the back, with the traditional screw-terminal connections on the sides in the device. These push-fit connections are notorious for loosening or failing, so professional electricians almost unanimously avoid them in favor of making very tight and secure screw terminal connections.
4. Respect Grounding and Polarization
Grounding and polarization are necessary to the safety of modern electrical systems. Grounding offers a safe path for stray electrical current caused by a fault and other overuse injury in a circuit. Polarization helps to ensure that electrical current travels from your source along “hot” wires and returns on the source along neutral wires.
Always follow manufacturer’s wiring diagrams when replacing a fixture, and understand—and use—your home’s grounding system to make certain grounding and polarization remain intact.
There are a variety of methods to test for grounding and polarization. A simple plug-in circuit analyzer tool, available for some amount of money, can make it possible to routinely check outlets to make certain these are wired correctly.
5. Box It, Clamp It
The National Electrical Code (NEC) mandates that all wiring connections be generated within an appropriate enclosure. In most cases, therefore an electrical box. Enclosures not simply protect the connections—and protect people from accidental experience of those connections—they also provide method for securing conductors (like electrical cables) and devices.
The rule the following is simple: you shouldn’t be lazy. If you need to create a wiring splice, purchase a junction box and secure the cables towards the box with cable clamps. Never leave a splice or another connection exposed or unsecured.
