Generic Wiring Diagram

A. Brake Control

B. 12 Volt Battery

C. Chassis Ground

D. Trailer Connector

E. Stoplight Switch

F. Automatic Reset Circuit Breaker

G. Turn / Brake Lights

1. The brake control must he installed with a 12 volt negative ground system. (To install with a positive ground system use Tekonsha Towing Systems P/N 3191)

2. Reversing BLACK and WHITE wires or improper wiring will damage or destroy brake control.

3. Be sure to solidly connect all four wires or brake control will not function properly.

4. Soldering is recommended or crimp-on butt connectors are a suitable substitution.

5. Route all wires as far from the radio antenna as possible to reduce AM interference.

6. Use of proper gauge wire when installing the brake control is CRITICAL; smaller gauge wire may result in less than efficient braking. Minimum wire gauges are as follows:

• 1-2 axle applications - 14 GA.

• 3-4 axle applications - 12 GA.

7. Collection of water inside the trailer connector mounted on the tow vehicle will reduce the life of the connector. To minimize corrosion build up inside the connector:

8. Connector terminals should be completely covered with dielectric compound (Tekonsha Towing Systems PIN 7200).

9. Mount trailer connector such that the brake line and ground terminals are not located near the 6 o'clock position.

NOTE: Please review your vehicle's Specific Wiring Section before continuing with the following Generic Instructions.

1. Using the appropriate hardware, connect the WHITE (-) wire to the NEGATIVE (-) terminal of the battery.

NOTE: Grounding to any other location than the negative terminal of the battery may cause intermittent braking or lack of sufficient voltage to trailer brakes. DO NOT ground the WHITE wire to the dash or other interior metal surfaces.

2. Connect BLACK (+) wire through an automatic reset circuit breaker (20 amp for 1-2 axles, 30 amp for 3-4 axles) to the POSITIVE (+) terminal of the battery. The BLACK wire is the power supply line to the brake control.

3. 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.

4. The BLUE (brake output) wire must be connected to the trailer connector's brake wire.

1999 New Style Convenience Center

• WITHOUT Trailer Tow Package

This connector will be available on all models without trailer tow option. However, the only wires that are useable at the connector end will be the stoplight (RED) and ground (WHITE). The 12 volt power line (BLACK) and electric trailer brake (BLUE) will terminate just under the vacuum assist outside the firewall. Therefore, the BLACK and BLUE wires will have to be run to the battery (BLACK) and trailer connector (BLUE). The mating 6-pin connector is available from GM (P/N 12171982) or Tekonsha Towing Systems (P/N 3025) that will interface with the 6-pin connector in the convenience center. Once again this connector will not be fully functional until power (BLACK) is run to the positive side of the battery through an automatic reset circuit breaker, and the electric trailer brake (BLUE) is connected to the trailer connector at the rear of the vehicle. These wires can be found under the vacuum assist in the engine compartment.

• WITH Trailer Tow Package

All vehicles with trailer tow option will have a mating 6-pin connector located in the glove box. Connect the brake control to the mating connector following GM instructions included with the connector.
