The yellow wire must be connected to a constant voltage source. You have the red and yellow connected to a voltage source that only gets power when the car is turned on. The yellow wire is for the memory. Check the fuse box for a fuse that has voltage on it when the car is off and the key is not even in the ignition. That is the type of connection the yellow wire needs. The red wire can stay connected to the place it is at now.

Are you using a harness that is made for installing a radio into a 99 neon? They sell them at most all places that sell car stereos. Go in and ask for an installation harness for your car and then you connect it to the harness that comes with your radio by matching the colors of the wires and you have a nice and easy install. It plugs right into the factory harness with all the connections you need.

Looking for instruction to operate an Alpine MDA-W905JB head unit in a Japanese car I just bought.


Go to the store and buy a mounting kit and wiring harness adapter that are for your car. There are alot to choose from and most are universal and come with instructions. You can get these at wal-mart or best buy. The mounting kit is meant to fill in the empty space left by the new aftermarket radio (your alpine). The alpine will have a metal sleeve around it. take this off and put it in the mounting bracket so it is flush. The sleeve will have little triangle shaped tabs on it. Bend these out so the sleeve cant fall out of the bracket or someone will be able to pull out your radio. Remove your stock radio by pulling off the trim around the radio. This is held on by clips, so be careful. There will be a couple of screws holding in the radio. Remove these and pull the radio out. Behind the radio there will be 1 or 2 wiring harnesses plugged into the radio. Unplug these. Then attach the wiring harness adapters you bought. These plug into the stock harness and have wires at the other end that are labeled. Wire the alpine wiring harness into the harness adapters that you plugged into the stock harness. If you want to you can unplug the harness from the alpine and wire it to the harness adapter before plugging it into the stock harness. The wiring diagram should be on the radio. If not the colors are pretty common.
RED = SWITCHED PWR LEAD (IGNITION)
ORANGE = ILLUMINATION
BLACK = GND
YELLOW = BATTERY LEAD
GREY = FNT SPKR RIGHT(+)
GREY/BLACK STRIPE = FNT SPKR RIGHT(-)
WHITE = FNT SPKR LEFT (+)
WHITE/BLACK STRIPE = FNT SPKR LEFT (-)
VIOLET = REAR SPKR RIGHT (+)
VIOLET/BLACK STRIPE = REAR SPKR RIGHT (-)
GREEN = REAR SPKR LEFT (+)
GREEN/BLACK STRIPE = REAR SPKR LEFT (-)
BLUE = PWR ANTENNA LEAD
BLUE/WHITE STRIPE = REMOTE TURN ON LEAD(FOR SUBWOOFER AMPLIFIER)
There may be RCA jack inputs in the back and these are for the subwoofer amp.
There will be a large black cable in the back and this is the antenna wire. Plug in the antenna wire from the back of the stock radio here. Yu may or may not need an adapter for this depending on the size difference between the wire and the hole it plugs into.
**Please note: if your car has a "premium" sound system that comes stock with an amplifier you will need to attach the power antenna lead from the alpine to the remote turn on lead on the harness adapter. If not when you turn on the radio/cd it will not turn on the stock amplifier and the speakers will not work.
I found this out with my 99 dodge avenger which has an Infinity stock radio. You can pop the trunk and look up at the back dash and see the small amplifier.
Once the radio is wired and the mounting bracket is installed, connect the harness adapter as well as the antenna wire. The new wiring harness adapter makes the wiring a little longer so you may have to stuff them back a little bit. Connect the harness from the alpine back into the back of the radio and slide the head unit into the metal sleeve until you hear a click. Before sucuring the mounting bracket and putting the trim back on it is a good idae to try the radio out so if there is something wrong you dont have to disassemble it again. When you buy the harness and bracket it will say on the packaging "nissan 84-94" or "Honda 83-99" or something similar. Look on the back for a complete list of compatable models.

Hope this was helpful. Please rate, and thanks!

well it depends on the car, if its a sunfire, theres a yellow wire that connects to the red wire that connects to the sterio, that yellow wire goes to fuse box maybe the power is constint the only way to fix that is to hock the red on sterio to an ignition source,

I have kenwood excelon ddx 7015 unit powers up but says a cord is not pluged in. Wanted to know if this unit has a internal or external brain box and if it has an external brainbox how do i find one


I have a DDX7015, and can tell you that the unit is completely self-contained. You can get a kds-p901 external 5.1 processing unit that deactivates the on-board processing brain; the 901 connects via fiber optic.
It sounds like your constant power (yellow) is not energizing. You can test that pretty easy - you should be able to hit the eject button with the car turned off, and the faceplate should lower.
Try pulling the unit out and checking the in-line fuses and the wires - you may find that the wires got crushed during installation. To test functionality, you can try twisting both red and yellow together, and connecting it directly to the battery. You may find that your 'constant power' in your dash is unable to supply the current this head unit needs (7-10A, if I remember correctly). If that's the case, you may need to run a dedicated wire out to the battery for the yellow. Make sure you put a fuse close to the battery. The fuse is not to protect the head unit, but to keep the wire from burning up in the event it gets shorted, so the fuse can be 20A or so (the head unit should have its own fuse). I hope your head unit comes to life - I've had 6 years of great service from mine, and it plays mp3s and wmas directly off of a data DVD, and works great with the KNA-DV4100 navigation system.
Good luck!

I need the wiring dia. for alpine 8020


If the alpine 8020 is a deck(head unit) the wire diagram is as followed:

Red: Accessory
Yellow: Constant Power
Black: Ground
Orange to orange/white is a illumination or dimmer wire.
White: front left speakers
Grey: front left (white black and so on usually the negative on the speaker connections)
Purple rear left (purple black = neg)
Green: Rear Right
And if a video deck(light green is park brake)
(which is usually just a ground) so legally it needs to be on your park brake but can be grounded to make it work.

Speakers? (Terminals larger one is positive, smaller one is negative) Place capacitors on if needed to filter out and clear up bass

Hope this helps couldn't look uo what a alpine 8020 was..

1. you can go here and get a wiring manual with right model #.
http://www.alpine-usa.com/US-en/support/
2. The red wire goes to ignition switch/key.
Yellow wire goes to constant hot/battery.
Black wire is ground.
Blue wire is for power antana you do not need to hook that to anything.
You can look at this diagram for a little more help it is not your radio though but it will give you a reference point to look at. All radio red,yellow,blue,black wires are the same on all radios.

Good luck with problem.

yes the wiring is different on the back of the head unit you have a black (earth) red (power) and yellow (memory) you will have to find you memory in the cars wiring it goes to straight power , also you can join red a yellow together and take it to the positive of the battery but you can only turn the cd player on and off but the actual unit its self .
