Relay for the horn / lights Extra (revised)

Many of us are not happy with the default sound horn motor / car that is less hard / rough, or also the standard that is less bright or powerless small.Di store partshop or automobile accessories, sold a lot of aftermarket horn that sound like Fiam, hella, Bosch , PIAA, Wolo, Hadley, fer, and it and so.Horn power large enough, unfortunately, the cable is installed on the default standard horn motor / car can not accommodate the power needs can be tersebut.Malah horn switch will be damaged quickly because every time you pressed , akan splash out a fire on the metal contact inside the long run will be worn, even to its plastic case akan meleleh.So also with the light of heaven is greater, will problematic same case with the above.
To complete the problem, we need additional support components, namely relay.Relay is a component that is used as the switch / pemutus flow to the load that is big enough, is controlled by electrical signals with the flow kecil.Dengan use the relay, the cable to the switch does not need to cable is bold, for the flow are connected to the switch is minimal.
Many of the relay in the circulating partshop, there are many brands such as hella, Bosch, Omron, etc., ... and many of them own in fake.I prefer to use a Bosch relay branded the original, as well as relaynya socket.
Following components that are required for this project .- Socket Relay Bosch brand + terminal konektornya Relay Bosch 4-foot type "0 332 019 453" - Fuse Box (box fuse) + terminal Connector-Fuse / fuse adjusted to the burden its flow. for example 10 Ampere Kabel .- thick fiber-diameter 5mm Terminal Ring
How to Install ..
There are 2 kinds of systems electricity to for horn or lights, which is controlled by a positive voltage and negative voltage.
Usually the system is controlled by using a negative voltage cable 2. One where the cable to the positive and one to the switch controller.
System that is controlled by voltage Positive, usually use only 1 cable from the switch controller. Take one cable from the ground or the negative body.
