We have everything needed to install the Prodigy P2, item # 90885, on your 1992 Chevrolet Astro Van.

You will need to start out with a 4-Way trailer connector at the rear of your vehicle. If you do not already have one you can use the 4-Pole Hardwire Kit Including Circuit Tester, item # 18252, to install one. Use the included circuit tester to find the correct functions behind the vehicle tail lights. Connect the white wire to a good ground, the brown wire to the tail light circuit, the yellow wire to the left turn signal and stoplight circuit and the green wire to the right side turn signal and tail light circuit.

Next, you will need the Brake Controller 7 & 4 Way Installation Kit - 10 Gauge, item # ETBC7.

This kit includes the 7-way and 4-way connector and all of the remaining wiring and parts needed to complete the installation of the wiring for the P2 and the trailer connector at the rear of the vehicle. Connect the 4-way connector to the 4-Way connector on the back of the 7-way connector provided in the # ETBC7 kit. There will be 4 wires remaining. Attach the white wire to a good ground connection on the vehicle frame. The blue wire is connected to the white wire in the duplex cable provided in the kit and the black wire is connected to the black wire in the same cable. The remaining wire, purple or yellow, is for the vehicle reverse light circuit. If needed, it is spliced into the reverse light circuit behind one of the tail lights. If not needed it can be tied up out of the way with a zip tie.

Next, run the duplex cable forward to the engine compartment. Avoid areas that could pinch, cut or melt the wire. Under the hood, cut this wire off with enough length to run the black wire to the battery and the white wire into the cab of the vehicle to the mounting location for the brake controller. Use the included 40 amp circuit breaker and attach the black wire to it and then the positive battery terminal. Connect the white wire in the cab of the vehicle to the blue wire exiting the back of the brake controller.

Now, use the leftover duplex cable and connect the white wire to the white ground wire exiting the brake controller and the black wire to the black power wire exiting the brake controller. Run the cable through the firewall to the vehicle battery and connect the white wire to the negative post and connect the black wire to a 20 or 30 amp circuit breaker and then to the positive battery post.

The final wire connection needs to be made to the vehicles stop light circuit. Using a circuit tester find the wire that only has a signal when the brake pedal is pressed. This wire is located under the dash behind the brake pedal switch. Attach the red wire exiting the brake controller to this wire.

All that is left is to mount the brake controller in an accessible location and set it up for towing using the instructions from the brake controller you select. Links to wire installation instructions, instructions for the brake controller and items mentioned are provided below.
