Warnings on Wiring
· As a general rule, never route the harness close to ignition wires.
· Route the harness very carefully to avoid chafing or undue strain.
· Secure wiring to the vehicle with wire ties with particular attention to the sensor
harness routing beneath the vehicle and in the engine compartment.
· Take care when routing sensor harness near hot exhaust components.
· Use a 5A inline fuse on the switched 12V power supply line (RED - Power/IO).
· Avoid cutting or extending the sensor harness.
· Use appropriate gauge wire (20 AWG or thicker) when extending wires,
especially RED (Switched 12V with min 3A) or BLACK (Ground) of the
Power/IO harness.
· Ensure all connections are secure and insulated from shorts to adjacent wires
and the vehicle structure. Utilize proper crimping and solder/heat shrink
techniques.
