Fiat Uno Radio Wiring - StuW

Hello, i'm putting my old radio into a friends fiat uno for him but i'm having a bit of trouble. When i took his original radio out it was clear the connections wouldn't fit into the new radio so i went off to halfords to a get an adaptor. When i tryed to put that in the connections wouldn't fit. So i took it back the bloke at halfords said that was the only one they did for the uno and when he looked connection at the back of the original uno radio he said it was very weird and not really seen one like it before. He suggested that i should cut them off and solder new ones on but as its not my car i'm doing it to i don't really want to do this. Has anyone any suggestions how to convert the original wiring to ISO?

Fiat Uno Radio Wiring - pastyman

First step,
Connect a test light to earth, then try each wire in turn and see which wire lights up the test light, that will give you the 12v live wire.
Next, use a continuity meter with a live feed built in, connect one to earth, try each other wire in turn, when it lights up/buzzes, that will give you your earth wire.
Next step, get a 1.5v C or D sized battery, the wires you have left should be speaker wires, gently touch the pairs of wires to the battery poles, listen for a crackle, this will indicate which pair of wires are for which speakers.
Connecting a 1.5v battery on the speaker wires is not enough to damage it, as is such a low current.
As for chopping wires, if it means soldering a better connection, i wouldn't worry about cutting the wires.

Hope this helps,

Pastyman..
