I need a wiring diagram for the aiwa stereo harness.

if you have the proper kit , the it is a simple matter of pulling the harness connector from a tail light assemble and inserting the harness on to the assembly the fitting the harness back on to it
the wires are color coded and all new trailer plug connections have the pin numbers for the color wire to get the correct lights working at the back
if you are not power or circuit savvy then get the towbar shop to wire it up or get an auto electrician to do the job

Greg, Check the attached links,instruction and guides stereo and speaker wiring, Good luck

If you are referring to installation and have the aftermarket wiring harness, The wires should be color coded. RED, YELLOW, & BLACK are power, ignition and ground. These should correspond to matching wires on the back of the head unit (CD player). Match the colored wires from the back of the unit to the same colored wires on the aftermarket harness and then connect them using wire connectors/wire nuts. Once you have them into the correct order the aftermarket harness should connect into the harness in your vehicle. I hope this answers your question =)

littlepyrodu, I would first back probe the wires going to the light bulb socket first to see if you are getting voltage to the socket, Sockets are prone to sometimes get to hot and resulting in the contact (inside of socket) to recess into the plastic housing causing it not to have contact with the bulb contacts. If you do not know how to back probe, you need a volt meter, cheapy will do just fine, and two small alligator clips (if the leads that come with the meter does not have them(some do) and two straight pins. First crimp the alligator clips on the free ends of the lead wires of the meter, set the meter for a 12 volt range (make sure your above 12 volt setting, less will fry your meter, take the two straight pins and stick them in the two wires going to the socket in question, space them apart a few inches so there is no chance in shorting out the two wires, clip on the alligator clips to the pins, turn on lights, if the meter swings to the left, reverse the alligator clips, wrong polarity, now you should have12 volts showing on your volt meter, if not, you do have a broken wire in the harness, that is as you stated " Fuse Is Fine". You also stated that the wire may have been cut,, you shouldn't need a diagram / schematic for that, the opposing color coded wire should be right there, either at the socket end or at the business end (under dash). Note: Look to see if there is a worn spot in the carpet, drivers side right at the side kick panel, there is a wiring harness under the carpet there that goes along the door threshold to various components in the car. My wife had a habit of resting her foot there all of the time while driving and wore a spot there and it exposed the wires located there, reason I know they are there. And is also where I connected wires from a remote starter for the door locks and trunk release and parking lights... If there is a worn through spot there or not, I would at least check there to see if a wire has been worn into or shorted out, all you have to do is pull the carpet out from under the driver side kick panel, enough to see the wires, then just tuck it back under the kick panel when done. Hope this helps you and anyone else with this issue.

Go to your local auto store and get the Hanes auto manual for this care and they should have a wiring schematic for you to follow also you can look your new stereo up on the web and find out what each colored wire goes to what!!! Good luck

Check out this link. Should have necessary info for you.

if you go to the parts store they make them ready to plug in you will have to just unplug the tail lights and plug the wire harness inplace of it then itll plug back into the original spot.

do you have harness going to your system if so you can match the wire colors together if not you will have to hardwire but keep in mind you will need a 12v tester with a light on it to check your ground lead your acc or ignition and then your direct or constant 12v you will have to check these three wires with a volt meter if you dont have a harness for your vehicle
