Currently have a goodmans radio in it which works, bought the car the other day. Ordered a new stereo for the car, I presume I'll have to wire it to the cigarette lighter which I've read on here about. When I took out the stereo I have these two blocks, one is the iso. I'm unsure what the coloured blocks are. No one seems to know. The rear speakers currently don't work either, I've not played about with them until I have the parts to fit Wednesday. Any advice is welcome. Ty
