Current Vehicle - Mitshibushi Pajero Sport Exceed 2018


Previous - Kia Sorrento 2009

I previously used a Kia Sorrento 2009 with a 2.4L Diesel Turbo Engine to tow our M26. It had a 2800Kg rated tow bar which was ideal for the boat.

All electrical installations are done as a complete independent system so as not to interfere with the existing circuit.


The Electric/Hydraulic Brake Controller

The Electronic Brake Controller unit ready to be mounted on the dashboard

As per the above diagram, the blue wire from the controller needs to be wired to the cool (no 12V) side on the brake stop light switch. The problem here is that there are 6 wires coming out of the switch and I was not prepared to fiddle with this circuit which could affect the ECM and complicate matters. Instead I used the wires from the stop light for the connection.

When the brake pedal is pressed, the cool side of the stop light goes live and provide the same 12V live signal contact as the switch . I used both stop lights wires on each side for better connection.

The Electronic Brake Controller secured on the dash board.



To ensure proper connection, I've used two pins off the trailer plug.

Pin 2 Reversing Signal.

Pin 5 Service Brakes.

Both plugs on the towing vehicle and trailer are configured the same. Over time, should the pins become corroded, two is better than one.


Installation of the 12V Anderson plug to power the Dexter unit on the trailer.

The red Anderson plug provides the 12V to power the Dexter unit as per the diagram. A 40amp fuse in the relay control module under the bonnet protects the system.

The heavy duty Anderson plug is for the 12V trailer electric winch. The left 50A Anderson plug is for charging the boat battery while driving. The small plug on top of the large Anderson plug is the rear camera connection. A 12V type pressure pump can also be connected to the 150A plug.


Other Electrical Modifications

All the relays, fuses, terminals and heavy duty cable connections are mounted on a plastic fire proof board. This independent module is connected directly to the two battery terminals without interfering with the car electronics.


A 150A fuse protects the heavy duty cables. The small red wires on the right are part of the module board. They connect to the master switches on the driver's side. Relays are triggered by the switches enabling the corresponding unit.


The wire loom from the bow of the boat running at the bottom to the battery charger.

Inside the anchor box are the two plugs that connect to the car using an extension cable. One is for the charger and the other small plug is to connect the rear camera.


The 20Amp 12V to 12V Battery charger inside the boat.


On the passenger side is the Ham HF and VHF Radio. In the middle is the CB Radio Front Panel. On the driver's side are five switches with Led indicators.

  1. Brake Controller.
  2. Ham Radio.
  3. GPS
  4. CB Radio.
  5. Rear camera display screen

There are two cameras, one underneath the number plate at the back of the car and a second camera on the rear frame at the back of the boat. This second camera is used when driving to have a clear view of traffic behind the boat.

The blue display shows the voltage of the battery charger.

The rear camera screen display mounts on the screen using suction cups. The HF antenna can be seen in front of the car.


Driving between towns in the outback can be very tiring. Music or conversation keeps us awake.

The GPS unit. The CB antenna can be seen on the right.

The rear view mirror and a Boab tree on the right. You guess it we are driving in the Derby area, WA.

Passing a road train with great caution.

The famous grey nomad caravan is approaching fast and a hand salute is imminent.. The HF antenna is seen on the left and the CB antenna on the right.


Not a place to sail the M26 but the Red Centre is certainly an incredible place to drive through.
