i am new to diy so am completely clueless. please forgive my ignorance! yesterday i cut through an alarm wire which goes to an unused (or not working) door sensor. i didnt think it would do much as the sensor doesnt work. after that the alarm wouldnt work (although cutting it didnt cause the alarm to sound so it cant have been tamper proof) so i reconnected the 6 wires. i want to extend the cable so that i can fit it under the carpet (i cut it because its ugly and wanted to get rid of it - covered in paint etc). i bought some 6 core cable thinking it would be easy to extend it but the colours are all different!! how do i know which colour to attach where, or perhaps it wont matter as long as it is the same at both ends of the 'extension'.
thanks in advance
