nissan micra audio re wiring

Hello, I need a little help with the re-wiring of a Nissan Micra x-reg (2000 model). I am putting an aftermarket head unit, and after purchasing the harness adapter for the standard ISO connector to replace the factory, the stereo still does not work. So i need to know what wire is for what, i.e power, memory etc. So i can re-wire the wiring. any help appreciated. http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_213755_langId_-1_categoryId_165626 thats the link for the harness adapter which i brought, if it helps.

problem has been re-solved, if anyone else was having a similar problem stick the antenna wire in the head unit as it acts as an earth wire hence the stereo will not work if not plugged in.
