Yellow w/black tracer is 12v+, black is negative
Blue w/red tracer is dash lite(not needed)
Get a AA battery, solder a wire to each end (this is called a "popper") Use this to find which speaker wire goes to what speaker, by connecting one wire from the AA, to one speaker wire.....and tapping the other wire from the AA to the other speaker wire. The speaker will make a "popping" noise. Mark the wire....and so on.

If you have no idea what your doing leave it alone. Find someone at a stereo store who can do it for you at a reasonable cost. It should not be that much $25 to$30.

NEED WIRING DIAGRAM


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 =)

Hi, please check to see if your colors match the ones below. If yes, then connect them to the aftermarket colors shown next. Assuming your factory installation has only four speakers, there should not be a lot of wires left over.

Need wire diagram for 2001 toyota tacoma for installing JVC kw-nt3hdt stereo or any advice


Hi, here are your factory wire colors/functions. Aftermarket stereos have a common set of colors, which should be in your installation diagram. The process is simplified if you purchase a wiring adapter for your vehicle. These are available for under $10 at most WALMARTs and auto parts stores or about any place that sells car stereos. In either case, I recommend you solder the connections or at least use crimp terminals. If you have any more questions, please let me know--I've done a lot of stereo installations.

My boyfriend is trying to install a cd player in my '94 cougar and there's this big grey wire thats taped up with the smaller colored wires. he dicided to cut the little plug thng off of the grey wire and...


Generally, the way I put an aftermarket cd-player in, is to use a new 'harness adapter' that connects to the old harness and has all of the wires color coded and labeled for easy installation of a new radio using wire nuts. I wouldn't try to cut into the existing harness, without knowing what was what.

What's the 'little plug thing' off of the grey wire?
