Head unit cables

[gazwhittle]

Which wires on the back of the adaptor to the head unit are + and - to the rear back speakers ?

Best off look in the manual for you're head unit and it will tell you which colours they are in the iso block, then you can simply trace the wires back.

not got the manual for it, soo wat colour are the wires before the iso block, the plug that is standard with the car ? cos then i will be able to trace it from that.
