Ive installed some aftermarket decks in late model Mazda's , try wiring your own ground to get the dash lights back... seems the wire that the factory deck grounded with acts as a relay or something with a negative signal running through it
Usually the "illumination" wires are yellow in the car and the stereo, and the negative should go to ground. I think that's how I hooked mine up. I can check it and get back to you later.
You connect the positive one (commonly orange/white) to your dash lights positive.
Illumination is the ability to lighten the screen or darken the screen with the other dash lights on the vehicle. normally you will have two orange wires coming from the cars wiring harness one with a white stripe one without. The orange/white wire will make the stereo dim or brighten with the dash lights. the solid orange wire will dim/brighten the stereo with the headlights. so if it is night you will have the headlights on, when you turn the headlights on the stereo dims so the light from the stereo will not blind you at night. while the headlights are off the stereo will be bright so the stereo light will be visible in the daytime
I bought a stereo to install myself. The pro-installer/salesman told me of this wire. You know how the stereo display light goes brihgt to dim when you turn on your head lights? This is a low voltage input to the stereo. Is this what you are dealing with?
Fuse ProblemIn your wiring you have caused a power wire for the lights to come in contact with ground. the closest one that i can think of is the cig lighter illumination wire. it is on the same loom as the stereo. either that or you have used the light circuit for power to your radio and have overloaded it. p.s. check the red with yellow stripe wire it is for illumination and it may be grounded or connected to your power to the stereo. I had the same problem after i did mine. I had hooked stereo ground wire to the backlight from the old stereo. It looked like ground when i checked it with multimeter. Make sure your ground wire is on steel or chassis.
Stereo systems obviously have illumination lights in them. Sometimes they will route these illumination wires to an area of the fuse panel which seems to affect the park lights, guage lights, etc. If the illumination wire(s) has touch an area of grounded metal, or another wire while installation, the problem is most likely a blown fuse. I hope you get this problem fixed. Good luck.
The illumination wire on a car stereo is meant for the brightness on the display. It is used to adjust the brightness of the display for seeing it during night hours.
A couple possibilities: 1) the insulation from a wire is damaged and the wire is in contact with the frame of the vehicle. 2) A socket is damaged or the bulb is put in wrong or damaged. 3) if the vehicle has a trailer light plug, it could be wired wrong or damaged. 4) the light switch or relay (if it uses a relay) is faulty and must be replaced. Another 2 posibilities are, if a new stereo has been fitted the earth for the stereo may have been connected to the illumination wire which tests as an earth when the park lights are off. To test this just unplug the stereo, replace the fuse and turn on the lights. If it stops isolate illumination wire and connect steroe to a proper earth. The other thing could be that illumination wire has been disconnected but not isolated properly and is shorting out behind radio.
Tap into the dash illumination fuse in the fuse block.
Did you check to see if you blew a fuse when you had it installed? Was the battery disconnected when the stereo was installed? Either that or one of the wires to the gauges has either been miswired to broken the circuit and maybe possibly not grounded.
I remove my stereo from my GMC Truck and now my lights don't work
