In the unlikely event of RF Interference try any of the following tips :
1) Refrain from using the vehicle chassis as a conduit for the earth return for the brake coils. Facilitate a separate
ground wire. (See point 3 below)
2) Mount the brake controller route all cables for the input and output of the brake controller away from antennas
and RF Equipment.
3) Use an as short as possible bifilar ( or twisted ) wire to feed the RBC and brake coils ( both active and return ).
4) Add a ferrite clamp over the RED, BLUE, BLACK & WHITE wires.
Wiring: Please ensure that a fuse is fitted in the Blue Wire (Brake).
The Brake Controller has four (4) coloured wires, BLACK, RED, BLUE and WHITE:.
The BLACK wire is the positive voltage power supply line.
The RED wire must be connected to a point that receives a DC Voltage equal to that of the supply voltage when the
brakes are on. Generally on most vehicles we recommend strongly to connect the RED wire to the cold side of the
brake light switch. If that is not the case on the vehicle then any point that receives a straight DC voltage, i.e. top
rear tail light, brake light relay or the wire connecting to the stop lights on the trailer plug (NOTE: Vehicles that use
the same globe/supply for rear and tail cannot have the RED wire to the stop light/tail lights directly. Please use the
alternatives listed above.)
The BLUE brake wire must be connected directly to the trailer brake wire.
The WHITE ground wire is connected to a grounded metal part of the dash,vehicle fire wall or directly to the negative
battery terminal.
* Please Note: An External Fuse Must Be Fitted (Not Supplied).

(Please check the polarity of your vehicles brake switch before connection)
Important:
A brake control unit that is not properly grounded may operate intermittently or not at all.
• Make sure all connections are secure.
• Do not connect the Black “BATTERY” wire to the fuse panel or tie into any accessory wiring.
Connecting to the existing wiring may damage the vehicles wiring and cause trailer brake failure.
• Do not reverse Black “BATTERY” wire and White “GROUND” connections.
Even a momentary incorrect connection can damage the brake control unit.
