Installing the heater starts by separating the vent panel from the heater box. The vent panel goes inside (‘ears’ pointing down), the power cable is routed through the scuttle (this requires a grommet to be split, passed over the cable and then glued back together). The two parts are simply bolted together and the heater cable connected to the wiring loom under the dash panel.

Next up is the heater control valve and cable. The heater control is a simple push / pull device just above the driver’s right knee. As other builders have noted the hole in the scuttle needed enlarging in order for the cable to pass through.

Connecting everything up involves cutting hoses and joining the pieces together as per the build manual although I chose to use Mikalor stainless steel hose clamps as they look neater and give a more even compression than the supplied jubilee clips.

The all important ‘submarine’ with its temperature sensor is installed at the rear of the engine and is connected with the green wire to the temperature sensor and an earth wire to the boss on the body of the ‘submarine’.
