Question about 1996 BMW 318
I need a wiring diagram so I can install a new stereo
HI, you do not need a wiring diagram, do you have a stereo already installed, if it is factory it is probably a baupunkt or a pioneer, although no bmw came with a radio as standard years ago, they where all fitted at the dealers. check for your constant positive with your meter. then find the ignition positive, ie.only on with the ignition, the constant keeps all your programmed channels. earth noemally brown on a bmw. but live in you're house!! green with a yellow tracer or line in your house is earth. then the feed to the electric aerial if you have one, if not forget about it, i think it is grey? then you just need your speakers, they are normally on a totally different plug, if you have 2 plugs thet are din plugs, or deutsch industrie norm. or in english german standard normal. It is a set size or measuremeent, din radio will basically fit into that size of hole in a dashboard.the speakers are normally gery with a black tracer, white with a black racer etc. if you touch these and do not get a shock they are speaker wires, ...only joking, you cannot get a shock from any of them..It should be easy enough to swap over especcially if you are just upgrading to anothr radio. just undoo each speaker with the stereo on to see where thet are located in the car, you cannot do to much damage. if the wires are say grey and grey with a black tracer, if you wire them up black and then grey with black tracer the wrong way around , they will still work, its not like putting the positive to the earth etc, on the radio.I doubt if there is actually a wiring diagram for basic bmw models, except for the 7 series top of the line, in the 80's the radio case for it to fit into was not even in the top of the range 5 series, we had to fit them in, the latest 3 series which had it in the dash came in from germany with a big plastic plate where the radio should be, datsun started fitting radios,as standard roll on nissan....
