Step 5: Connect the Brake Light Wire
The brake light wire is typically red. Connect the red wire to the vehicle’s brake light circuit. This will allow the trailer’s brake lights to function properly when the vehicle’s brakes are applied.
Step 6: Connect the Reverse Light Wire
The reverse light wire is typically blue. Connect the blue wire to the vehicle’s reverse light circuit. This will allow the trailer’s reverse lights to function properly when the vehicle is put into reverse.
Step 7: Connect the Auxiliary Power Wire
The auxiliary power wire is typically black. Connect the black wire to the vehicle’s battery positive terminal. This will provide power to the trailer’s auxiliary devices, such as electric brakes or a charging system.
