The Wiring Loom
According to howacarworks.com "the electrical wiring in a car is a system of colour-coded wires called the loom. Where several wires run side by side they are bound together with insulating tape or plastic sleeving". It can also be called a wiring Harness. In the GT6 it is divided into two sections, one serving the front of the car, and one the rear. These are linked under the dash by a connector like this:
The split is roughly as below:
CIRCUIT | LOOM |
Front Parking lamp | Front |
Hazard warning | Front |
Headlamp flasher | Front |
Heater | Front |
Horn | Front |
Instrument illumination | Front |
Temperature indication | Front |

This loom is protected by only three 35amp fuses as follows:
