How do I know which wire is for my brakes?
It is usually underneath the dash just above the brake pedal. Look for a small switch attached to the brake linkage that has two wires connected to it. Connect the pigtail of the test light to a good ground.
How do you connect a brake light switch?
This wire should lead to the brake light switch. The switch itself is connected with a plug, so you may need to splice your power wire to the power wire coming out of the plug. Once the switch has power, you need to connect the output wire from the switch to the rest of the brake light wiring harness.
Where is the Black Wire on a brake control?
The BLACK wire is the power supply line to the brake control. 4. The RED (stoplight) wire must be connected to the cold side of the brake pedal stoplight switch. Splice down line from the switch; DO NOT disturb the position of the switch.
Where does the brake wire go on a trailer?
The RED (stoplight) wire must be connected to the cold side of the brake pedal stoplight switch. Splice down line from the switch; DO NOT disturb the position of the switch. 5. The BLUE (brake output) wire must be connected to the trailer connector’s brake wire.
Do you need a switched power supply for a brake controller?
Brake controllers should be powered directly from the battery via a circuit breaker. There are two reasons to avoid using a switched power supply; Firstly – you want to retain trailer brakes even if the ignition cuts out unexpectedly. Secondly (on inertia controlled units) – removing power will clear the unit’s calibration.

What do Butt connectors do for a brake controller?
Butt connectors help to make connections between wires. Ring terminals attach to the end of wires and hook around battery posts and circuit breakers. Zip ties help to bind loose wires together and prevent them from interfering with vehicle components such as brake and gas pedals. Find a suitable location to mount the 7-way connector.
What’s the name of the wire for the brake controller?
The first wire (black) runs to the vehicle’s battery to supply power to the trailer connector. This wire is called the “12 volt hot lead.” The second wire (blue) runs to the brake controller to supply power to the trailer brakes. This wire is called the “brake wire.”
How do you install a discovery brake control?
Using a 10/12 gauge butt connector, attach the white wire from the battery area to the brake control’s white wire. Run a 10 gauge blue wire from the tow vehicle’s trailer plug ‘brake’ terminal to the brake control. Using a 10/12 butt connector, connect this wire to the brake control’s blue wire.
