Changing Out Radio and Wiring

[michael228]

Hope someone can help! I am changing out my stereo and speakers. The person who had this car before me must have had some High Dollar Stereo in it because there are all kinds of dead ends and harnesses that are in the radio area but go now where on this current radio.

I have a new harness for the new Stereo System and that is easy enough to figure out which wires go where specially for the new speakers by the given instructions and color coding. The issue I have is the power wires.....looking at the Original Nissan Harness Plugs that are still there but I will not be using and the new Harness and the instructions to attach the red and yellow power supply leads from the new harness to................?? I am looking at the existing harness that is still in the car and trying to figure out........What color wires do I cut and attach to the new harness red and yellow wires power leads?? Anyone know? Thanks! Mike

the yellow wire goes to constant 12 v and the red go to switched 12v. always double check before splicing.

Yeah you can either hardwire it using the colors that were posted above or go to Circuit City or Best Buy to get an adapter harness so that all you have to do is match colors.
