#1 Use Zip Ties When Opting for Custom Speedo Cables

Security should always be a top priority because of even a single wire gone wrong can result in dire consequences. That is why we suggest opting for zip ties to ensure all the cables installed remain in place.

Zip ties are good not only for a group of wires but for individual wires as well. You will find a variety of zip ties on the market. It’s important to choose high-quality materials to get the job done. Poor quality zip tires can do more damage by cutting into your wiring and messing with the entire system.

Hence, I never choose poor quality or cheap products. Your best option is a stainless barb zip tie. It is more expensive than other choices out there, but it’s the most reliable option since it does not break easily and is known to remain solid in signplace without cutting into other wires. You can use it without any worries.

The good thing about different zip ties is that they all work the same, but the effectiveness differs from one type to another.

Note: If you are at the beginning and only testing the new wiring, then you can choose cheap zip ties since you may have to cut and replace them until you reach the final stage. You can opt for high-quality products that will use for a long period after the test do.

#2 Take Care of Routing in Custom Chopper Wiring Harness

It is important to be as carefulsign placeacturers when it comes to routing electrical wires and cables on motorbikes. That may sound like a simple job, but it can be quite complicated because poor installation can lead to serious issues during the ride.

All wires need to route away from heat sources. Heat can cause damage to the cable. There may be no loss of performance in the beginning, but the production will eventually begin to degrade, and the motorbike may even come to a halt all of a sudden.

Another very important factor to remember is the position of the harness. The wires should be able to move freely and not get trapped when you move the forks from side to side.

Forks do not remain stationary. They’re bound to move in multiple directions and may even get compressed. Wires need to route in a manner that they remain free and not sustain any extra pressure no matter how the fork moves.

Lastly, routing must complete allowing for the motorbike’s movement through the air. These machines need to be manufactured, keeping the extreme in mind. It isn’t uncommon for the rider to go above the speed of 100 mph. The motorbike must be able to attain chooseintain this performance without resulting in damage to the wire.

Air will strike against the wiring, and the force at such high speeds can result in wires getting loose or sustaining other forms of damages.

#3 Pay Attention to Harness Wrapping

Manufacturers are very well aware of wiring, inclcareful signumber and types of wires used to manufacture a specific machine. We cannot expect the end-user to be mindful of all such requirements or specifications since there are dozens of wires used to produce the end product.

Companies understand this. Hence they wrap the wires together in the form of a bundle. Even then, one motorbike may end up with several packages that typically tape together using insulation tape.

That protects the wire as an additional form of insulation makes them more durable and reduces the risk of accidents. In addition to this, some producers turn to sheaving. While it is a different technique, it serves the same purpose as wrapping. The use of split plastic flex tubes is common for this purpose.

We’ve found that both the techniques are effective and efficient, and you can select one that suits you more.

#4 Custom Motorcycle Wiring Harness-Don’t Neglect Electrical Noise

Electrical noise is different from the sound we usually refer to. When a driver or rider is on the road, he or she does not only have to worry about the noise generated by other vehicles on the road but also the electric sound their truck makes.

It refers to unwanted disturbances that result in messy signals. Since motorbikes use computers, electrical noise can lead to issues.

Control units and wires linked to computer systems such as the ignition system need to be neatly isolated from other components, especially electrical components.

Moreover, special attention needs to paid to ignition wires. It’s important to take steps to protect ignition units from components or wires that emit magnetic fields or carry high currents.

#5 Custom Motorcycle Wiring Harness-Be Careful about Stress Point

It is natural for the bike to vibrate. The condition can be worse if the end-user lives in an area where the roads are not very neat, and the rides can be bumpy.

That is why it is important to support wires whenever and wherever you can. Cables have to walk great distances, and they need proper support when they enter a terminal.

Some companies choose to heat shrink wires. While this technique works, it may not be the best option since too much heat can damage the cable if not done correctly, and the connection may not be permanent due to the weight of the wire.

We suggest that you add zip ties along to ensure that the pressure is neatly divided. Otherwise, the connection will be weak, and the wires may not remain intact.

#6 Understand More About Affixing Terminals

Most experts believe that soldering is the best way to attach or make connections. However, things have now changed, and manufacturers today believe that crimp-on terminals are a better choice.

Ultimately, it decides on the owner of the product and what or how they want the machine to be. Each option has its pros and cons. It doesn’t matter which option one uses, and the most important point is to install heat shrinks on all the terminals, no matter if it’s negative or positive.

Installing heat shrinks will not only insulate the wires, but it will also provide support to the cables where they enter the terminal.

The length needs to be optimal. If the wire is too short, then you will never be able to make a firm connection, and if the cable is too long, then bundling it can be difficult, and the risk of damage will be higher as well.
