1985-92 Volkswagen Jetta Stereo Wiring Information

i and trying to wire it up and im not getting any light to the screen. i cant see anything. i am getting power because the disk drive turns on and i can here the motor inside spinning. Also there is the Blue/*********** CONTROL WIRE. i have no idea which one this connects to.

Someone please clarify whats going on with my car stereo haha. thanks

your blue/white wire would go to the amp if you have one. It would be the wire to tell it to turn on or off.

Just another note, my '95 has two switched hot wires in the harness. One does not carry enough power to turn the amp in my alpine head unit on. All the lights turn on and the disk spins up but there is no sound. Both switched hots were the same color wire too.

that happened to me before and i just thought that the speakers were wired bad so i took it all out. i got power but it wont light up. can you tell me how to make it light up? haha cause then i could see if im playing a trackl. And would i need to buy an amp? i have two 250 watt speakers mounted in the back panel. thanks

well if you want to power them at full wattage you will need an amp but they will still work with out one

There may be a dimmer/illumation wire on your harness

 

[WolfsJetta]

yes the illum wire. i connected mine to constant 12v

 

[92mk2 hess]

so i should connect what wires together? the illum wire to the constant and that to the wire to the wire the constant connects to on the stereo?

Chris, the problem is probably the fact that your jetta doesnt seem to have a ignition 12+ wire(at least thats what the info you provided says) i'm not real sure about the mk2 but i can tell you that the yellow wire on the Kenwood should go to a 12+ source which again accordijng to your info should be your red wire on the jetta harness. That leaves the red wire from the Kenwood which needs to be hooked to a 12+ source when the ignition is turned on (this could be wired to the red wire as well but the unit would not cut off with the ignition). The blu/white will not be used and your unit doesnt have a illumination circuit so it works off the ignition or the red wire on the Kenwood. Invest in a test light if you havent already done so. Both the Red and the Yellow on the HU must have 12+ in order to work. If they both have 12+ and you have a good ground, (brown on the Jetta) the unit should power up, if it doesnt its toast.
