If you are going to be installing the Hopkins Brake Controller, # HM47295, and the 7-Way plug at the same time on your 2006 Nissan Murano, I would recommend getting the brake controller installation kit # ETBC7, which includes the # 37185 adapter that would plug into a 4-Way on the vehicle, as well as everything else you will need to complete the brake controller installation.

If you do not have a 4-Way on your vehicle, then you would need the CURT T-Connector Vehicle Wiring Harness with 4-Pole Trailer Connector, # C56105 that is for the 2006 Nissan Murano and would plug into the vehicles factory wiring harness at the taillights.

To install the adapter, # 37185, plug it into the 4-Way on the back of your vehicle and there will be four additional wires sticking out the back of the adapter. The four additional wires are white, black, blue and purple. The white is ground, it needs to be attached to the vehicle frame. The black is 12 volt power lead wire, it goes to the vehicles positive battery terminal, with the 40amp circuit breaker included in the # ETBC7 kit. The blue is electric brake output wire, it will connect to the blue electric brake wire coming from the brake controller in the vehicle cab. The purple wire is an auxiliary wire, and can be used as a 12v power source, or to power a reverse light or reverse lockout function if needed. If not used, this wire can be tied up out of the way.

The Hopkins Brake Controller, # HM47295, includes a pigtail that you will use to hardwire the unit to your vehicle. The pigtail has four wires that will need to be connected as follows:

The 4 brake controller wire functions are:

White: Ground, attached to the negative battery terminal.
Black: 12v lead, attached to the vehicle positive battery terminal with either the 20amp or 30amp circuit breaker included in the # ETBC7 kit. Use the 20amp breaker if your trailer has 2 to 4 brakes, or the 30amp if the trailer has 4 to 8 brakes.
Blue: Electric brakes, attached to the blue electric brake wire from the # 37185 adapter.
Red: Stoplight switch, located at the top of the brake pedal. Use circuit tester like part # 3808 to test each wire exiting the switch. Tap the red wire into the circuit that only goes hot when the brake pedal is applied.

This will give you the Hopkins brake controller and a 7-Way plug on your 2006 Nissan Murano.

I would not have a wire diagram for your 1972 Fireball travel trailer or for any of the internal components on the trailer.

I am sending a link to the brake controller installation with the ETBC7 installation kit. Also I am sending a link to a trailer wiring page which will show how to wire the 4-Way T-One connector to your vehicle.
