Ive just brought a second hand radio from e-bay, i think it was from a 1991 disco so i thought it would plug straight into my 1991 defender! Not so easy, different plug and all the other wires have been cut. Is there any where i can get a wiring diagram? Theres 16 different wires all together, what the hell are they all for?

are all the wires from the plug on the sterio un cut or molested in any way if so then take it to some where like halfords and get an adapter for it to go in an UN wired vehicle and then just work out what your wires do by either traceing them or with a wireing manual but if its the other way round witht the plug cut off the sterio then cheak out the rave disks under the disco section for the wireing coulors for sterio connects and then the same but for the defender

to double check wiring get or make a small test light orborrow a meter..
connect one side to ground. IE the cig lighter. and probe the wires one by one till you find a live wire.. that wire will be the live wire for the memory. now do the same with the ignition on and check again.... and so on etc
to find the speakers get a small "AAA" batery and do the following.
you need 8 wires ie 4 pairs of speakers to pair up from in the dash.
normally the colours are simerler. so start there.
get hold of 1 wire and put it to the + side of the AAA battery.
chose another wire and gently tap onto the - side of the AAA battery
when you hear a low pop or crackle that is a correct pair. tape up and mark as RR/RL / FR / FL etc
to check the pollarity , if the speaker moves out when you apply a volt into it then the +- are the correct way round . if it goes in then -+ need swapping..
i hope this is of some use to you
