There is a feed for a radio or CD. This feed can also be used to power an alarm.
Interior light and door switch wires are provided.
There is no additional wiring specifically for alarms.
It is supplied complete, is made to measure, fully terminated, includes all battery leads, includes fuse box with fuses and has all relays etc.
It is fully colour coded to BS standards and is supplied with a connection chart.
It also has the Hazzard lights circuit fully intergrated. Some other looms require a separate Hazzard lights circuit to be added.
Hope this helps.
