The first step in understanding Ryder Bypass Relay wiring diagrams is to get familiar with the symbols and layouts used. For the sake of clarity, each symbol is color-coded to help distinguish between the various parts of the relay. The symbols also indicate the type of connection, whether it is for instance electrical, ground or signal connector. I always wire up my own towbars and the vehicle specific wiring for my Mitsubishi stipulates one 25 amp circuit, one 20amp circuit and one 15 amp circuit as required by ISO 11446. This smart bypass fits virtually all cars, handles cars with standard or modulated circuitry (e.g. two functions in one bulb) and has a quiescent current of zero. Ryder Bypass Relays are a common tool in automotive engineering, providing an easy and reliable way of bypassing components - such as electronic throttle bodies, circuit breakers and low current circuits - to ensure they remain protected while the automotive runs. It is important to understand how to read the wiring diagrams associated with these relays.

I'm afraid you are wrong with your adding up. Worst case scenario, 3 brake lights- don't forget high level light, could be 63w. Indicators x2 don't forget hazard lights. Side lights, don't forget all the side repeaters which may not be LEDs, my docs allow 52watts each side, fog light, there could be 2, therefore 42watts. All in all it adds up to nearly 300w, i. e. requiring a 25 amp wiring and fuse just for the trailer lighting.They use smart logic to deal with cars that have one bulb handling two functions (e.g. brake lights and sidelights sharing the same bulbs). The signal wires to the car’s rear lighting loom are protected so that only a milliamp can pass from the car to the relay and nothing can pass from the relay to the car. Before using a Ryder Bypass Relay, it is important to make sure that the wiring diagrams contained within it are properly read and understood. Ignoring the diagrams can lead to serious malfunctions, potentially causing the device to overheat or even increasing the chances of a short-circuit. In the worst-case scenario, a catastrophic failure can occur resulting in a huge repair bill. Therefore, it is crucial to pay close attention to the safety procedures outlined in the Ryder Bypass Relay wiring diagrams before attempting to use the device. You can use the polarized symbols — those denoted by either a (+) or (-) — to establish whether a specific part of the device is connected to the electric charge or not. The part of the device marked with (-) will not be connected to electric current, and the dot on the left hand side of the symbol indicates the trajectory of electricity.

UK Scottish Highlands and Isles w e use a two-day courier service for mainland UK, but please allow up to five working days for your delivery. Route your power source cable(s) from the relay to the vehicle fusebox using a PowerTap connector (TV1645-1 or TV1645-2- not included) DO NOT insert the (15amp) fuse yet.

NOTE: One fuse protects: Stop lights; RH tail light; LH tail lightThe other protects LH flasher; RH flasher; Reverse; Fog AND will switch off all circuits if it fails
