6. We recommend that the wiring loom is positioned away from existing wiring looms on the
motorcycle to avoid any possible electrical interference issues.
7. When the wiring is in position on the motorcycle, we strongly recommend that all connectors are
protected with either electrical insulation tape, waterproof sealing tape or heat shrink tubing
(be careful not to damage the cable when fi tting heat shrink).
8. Both the negative and the positive battery connections are fi tted with a ring terminal. This will allow
them to be bolted to the battery terminals. It is both preferable and the easiest option to connect the
positive (+ Red wire) straight to the positive (+) battery terminal so that the switch receives suffi cient
voltage from the vehicles charging system.
9. The negative or earth (Black wire) should be connected to the negative (-) battery terminal.
10. The control box (see drawing below) can be positioned under the motorcycle seat or near to the
battery. But we recommend that it is kept at least 1” or 25mm away from the battery at all times.
11. If the switch must be connected to a switched ignition supply feed, please ensure that the wiring
harness is connected to main ignition cabling which can take the extra load of up to 4 amps.
Problems are commonly found to be caused when connections are made to horn or any lighting
circuits.
Typical problems experienced could be:
- The switch may not come on
- Fuses failing in the fuse box
- Overheating of wires on the bike
- Indicators or lighting malfunctioning
