- Page 10 WIRING DIAGRAM IMPORTANT: Make sure that both positive and ground connections are made directly to the tow vehicle's battery. Connecting to existing wiring or chassis ground, other than the battery terminal, may damage vehicle circuits and could lead to trailer brake failure. Mount a 30 amp, auto reset, circuit breaker as close to the battery as possible.
- Page 11 IMPORTANT: When passing wire through sheet metal, always go through an existing grommet, add a grommet or use silicone sealer to protect the wire from sharp edges. Feed two 12 gauge, or larger, wires, one white and one black, from the mounted brake control to the battery area.
- Page 12 For all other vehicles, use a test probe to find the cold side of the stoplight switch. Probe the switch wires until a wire is found that is only on when the brake pedal is pressed IMPORTANT: Once a cold side wire is found, test to ensure that the wire is not grounded when the pedal is in the up position.
- Page 13 Test Drive In an open area, such as a large parking lot, drive forward and apply the trailer brakes using the manual control. If the trailer brakes are weak adjust the output control to the right. If the trailer brakes jerk or lockup adjust the output control to the left. Repeat this step until firm braking is felt without lockup.
