Ok I just installed my new VRVD630 DVD player in the dash of my firebird, and there is a questionable 2 wire plug that is clipped on the back of the original head unit that I am not sure what it goes to the 2 wires on the plug are a dark brown and a dark grey color. and it has a metal clip that clips on the back, seperate from the three stacked 4 wire connectors that are in the E groove.

So this is the problem after hooking up the new stereo I hooked the dark brown wire to the ground wire thinking it was a permanent ground and the other one was a switched ground... well it blew a fuse... I replaced the fuse but the headlights now do something weird and I don't know why... heres an example of what it does:

I turn on the headlight switch headlights come up... i toggle it back down... lights turn off but the headlights remain up...

I toggle it just into the other lighted mode without the headlights... then toggle it back down and finally the headlights now drop down.... its weird.

anyways I have the dark gray and dark brown wires not connected to anything ... both of these go to the clip on connector in the back of the original unit... not sure what to do with them, or what they were for... but it seems they are related to my dash & headlight lighting system.

All help greatly appreciated... dejavue for some reason.

 

Those wires are for memory and lights on the radio.The brown is in the same circuit with the park lamps and the orange with the lighting the instruments/console.Always keep in mind with GM black is used for ground wire color.brown isn't generally unless for speakers.

 

Hmmm what are you supposed to hook them up too after you install a new head unit? I have them hooked up to nothing right now and the headlight motors are acting funky as described above.

 

Apparently the glitch is working itself out .. i fear i have a bad headlight switch and am not sure if this is something easily replacable... anyone know anything about these headlight switches is it common they go out.. i think maybe the power surge and blowing the fuse may have had something to do with damaging my headlight switch .. i had the brown wire grounded out to my radio when it was not a ground lead as i learned.

 

It's not totally impossible for a first timer, i'm not fully aware of the '83 dash being i have an 88, but i'm assuming it's pretty close. On the '88 you have to take the dash bezel that goes around all the guages off, like 2-3 screws underneath the dash pad up top and 2-4 underneath the dash. Once you get the bezel totally off you will be able to see the switch unit. Mine is held in by two 7MM screws, and from there as far as i know unplug and replace. Good luck!

I don't know about '83...i was making a blind assumption, sorry if i'm wrong...but my '88 has the same plugs as the "89-90" section under GM/Saturn. My '86 berlinetta has the same plugs, but i haven't looked at my '84 belinetta, thought it was the same. Sorry if i was wrong.
