Switches for wiring motorcycle accessories are primarily designed to be used for your motorcycle rated for load as well as weatherproof. Those switches that lights up with built in type of LED are excellent ideas. Oftentimes, these switches can just be mounted near the cluster of the instrument or even with bracket or handlebar mount. The bosch-kind of automotive relay can also be used when the current draw is relatively high the same as auxiliary lamps.


One of the most difficult parts of the wiring project is in searching for the right connectors. You will usually need 2 different types: one which will interface with another or existing wiring in your bike/motorcycle and another one that will connect between different accessories.

It will just be right if you take a picture of the connector. The SAE connector is also simply suggested for the connection end of the accessory. As per the plug end, it usually has 2 connectors which really complement well to each other. The first one has insulator and the other one does not.

And, you must never ever replace the fuse just so you could allow more current.
