Installing a Brake Controller from Scratch on a 2000 GMC Safari Van

Expert Reply:

In order to install the Prodigy P2 brake controller, # 90885, you will need to hardwire it using a 4 and 7 Way Installation Kit, # ETBC7. If you do not have a 4-Way already on your 2000 GMC Safari, you will need to install one first. You will need Draw-Tite Wiring, # 18252. This is a basic hardwire harness. Yellow is for left turn and brake, brown is for running lights, green is for right turn and brake, and white is the ground. I have included a video showing how this harness is installed.

With a 4-Way installed, plug it into the back of the 7-Way. Ground the 7-Way, and attach the yellow or purple wire to a reverse light wire. Next, use the included duplex cable and attach the black wire in it to the black wire on the ETBC7 and the white wire to the Blue wire in the ETBC7. Then route the duplex cable under the vehicle and up through the engine compartment. Attach the black wire to a 40 amp circuit breaker and from there to the positive battery terminal. Route the white wire through the firewall.

The white wire will attach to the brake controller blue wire. The black wire on the brake controller will get route through the firewall and connect first to a 20 or 30 amp circuit breaker (see instructions for which size to use) and from there to the positive battery terminal. The white wire on the brake controller will get routed through the firewall to the negative battery terminal. The red wire on the brake controller will get connected to the stop light switch above the brake pedal. You will need the wire that carries a signal ONLY when the brake pedal is pressed.

To mount the brake controller, use the Mounting Pocket, # 7686, or the Replacement Bracket, # TK5904. I have included a link to an FAQ on installing a brake controller from scratch and a video showing installation of an ETBC7 kit.
