Maplin code: ZV00 Cut it in half and stick on molexs and you have 2 power cables for your inverters! £2.99, cheaper then £4.99 for audio cable to hack up. Also Manchester maplins (oxford road) has yellow and white CCs in stock and he said he was due more in very soon!
I used Rapid Assembly LED Holders from Rapid Electronics. They're basically like the front panel connectors that attach to your mobo. The LED goes into connector bit, and you just crimp some molex pins on the bare wires at the other end. 40p each
