Is it necessary to connect the illumination wire in your stereo?

no, not necessary. Some vehicles provide a control wire right in the stereo harness, others do not. The use of it all depends on wether you want the display to dim when you turn your headlights on or not. ------------- a true canadian eh!

what if you dont use a harness, how do you test for this wire? and what are the wires that **** up your car if there not connected (not using a harness) like some lights dont turn on and you lose the door buzzer.

In my opinion, if you don't use a wiring harness adapter, you are being very foolish. ------------- Support the12volt.com

what vehicle is this for? need some info first before we can say if you can skip some wires. And yes I agree for the feww dollars you have to shell out for a wire harness kit, it ends up as good money spent.

Why? Because 1) you won't be damaging your vehicle by cutting into the factory wiring. 2) less chance for error or stupid mistakes since all wires are clearly labelled on adapters. 3) easier to return the car to stock when and if you decide to sell it or scrap it and want to pull your system out first. 4) much more professional install technique instead of amateur hack job. 5) less chance you'll cut a wire that needs to remain intact. 6) much easier to change something later. And there are other reasons I'm sure. ------------- Support the12volt.com

In order for the radio to dim, do you have to ground the illumination wire, feed +12v into it, or what. My HU is a Pioneer DEH-4700mp ------------- There are 3 kinds of people in the world, those who can count and those who can't

Ah for the first time I slightly, repeat slightly disagree with DYohn. I was in this business before there were harnesses and while I agree with every point DYohn made I've found my installation guys learn individual car's wiring quicker if they have to figure it out themselves. Of course it also gives you a chance to save the customer $20 if you are close on the deal. I always give my customers the choice after explaining the situation. As for do it your selfers, always use a harness. , ------------- There is no such thing as free installation!

Alright out of different curcumtances previous stereo has been stolen the connector is cut off something. The point is being able to do any job without being dependant on one thing. Stop writing to me use the harness ok i know its good and faster but I want to know what to check for and shhh when your connector is missing for whatever reason other then the main connections speakers, amps, attenas, power, key switch and ground. Please i just want to know how to do it without it in case of emergency.

Look for the factory amplifier either under the radio, or behind the glove box and see if the harness is the same. If it is- connect to that harness to bypass the factory amp. If it's different, be sure to connect the amp turn on lead in the harness to power up the factory amp. No, the illuminatio wire is not necessary for sound.
