Relay Wiring Diagram
A relay is typically used to control a component that draws high amperage.
The relay allows full power to the component without needing a switch that
can carry the amps. The switch only controls the relay. The relay then
provides a direct connection to the battery. It should be noted that either the
power(86) or ground(85) in the relay control circuit can be switched. In the
case of a horn, the horn button would be used to switch the ground lead(85)
and power(86) would be provided directly from the fuse box.
This is a typical wiring diagram for a standard relay installed for
headlights, horn, fuel pump, electric fan, etc. If the relay has a
5th terminal, it is not used.

Engine Cut
Relay Connection: Connect a relay as below picture shows:
Calculate the correct VCC value according to relay’s parameter to comply with the
following requirements:
Output open drain sink voltage (ineffective) 45V max
Output Low voltage sink current (effective) 500mA max
Normally two green wires are connected solidly (P1 and P2 are Normal Close[NC] in the
relay), when output is open (Output be low voltage), two green wires will disconnect, the
engine is then cut.
