I was looking for this a while ago and couldnt find it anywere and I know a few people who need to know this so I figure I'd post it.
The sunbird tails have one light for brake and another for signal, teh phase 2 cavy tails have one light for brake and signal, which if youve ever tried to swap them you see an imediate problem. To solve it first get the conectors that hold the bulbs in off the pahse 2 cavy and just cut the wires off a few inches down so you have enough room to work with it, then cut the bulb conectors off the sunbird harness.
On the left side (drivers) (wiring is slightly diffrent on the right)the cavy conector has a yellow, brown and black wire, connect the yellow wire from the sunbird harness to the yellow on the cavy conector, then take the blue wire from the sunbird harness and conect it to the yellow wire also, then take the brown wire (on some cars theres more than one)from the sunbird harness and connect them to the brown on the cavy connector and take all the blacks off the sunbird harness and connect them to the blacks on the cavy connector, then tape them all up or shrink wrap or how ever you do it and move on to the other side.
The right side (passengers) its pretty much the same but instead of a yellow wire you have a green one.
Most of its pretty strait foreward stuff, the only real problem I ran into was the blue wire but I figured it out pretty quick.

Oh, thanks, now that Ive gone through 3 sets of Cavy wiring harness! Get it for ya in a couple days, eh!?!?!?!?? More like a couple months!!
But thanks, I'm sure I'll find it quite useful
There is a problem with your howto. Your turn signals wont work when you are pressing the brake.
I believe this is a wire up near the brakes somewhere. I remember reading something about cutting a wire on the brake switch to do the opposite of this swap...

On the Cavy the brake lights run into the turn signal switch so when you hit Left turn signal for example the signal switch kills the left brake light and flashes it.
The sunbird has always had a seperate bulb for the turn signal so i really doubt their brakes are wired into the turn signal stalk as in the cavy. Therefore your brakes would illuminate the second filament and the flasher would have nothing to flash.
Another option might be to get a Cavalier signal relay? Can anyone confirm whether or not Cavy and Sunbird turn signal relays are different part numbers?
I think it must just be me but I think the sunbird tails are better than the cavie ones
I don't understand putting all cavie stuff on a sunbird, just go buy a cav instead

lol, yeah.......about that...........
I just couldnt get a hold of the guy to figure out how he did it so I just got ambitious and went and figured it out myself, but it looks like I still have an issue.
I never tried signaling while on the brakes, I'll have to look into that, I just have tio find a way to break the circuit in the blue wire when the signal goes on. I have a wiring diagrams for the J's but it only has the tail light diagram for one type of tails so its not much help.
thanks Pezed

Its the turn signal stalk itself that does kills the correct brake light. It says right here in my service manual
my stalk wont kill my turn lights, and i have bird tails...

Im doing basically what Tyrin's how-to says, but putting diodes in each wire before it gets to the splice...

How do you plan on wiring diodes to do this?? Its not possible.
what you need to do is just wire up the turn signal stalk like it is in a cavy. it shouldnt be hard to do.
Well then, do you have pics...
Also, I got a buncha 12V in-line diodes at Radio Shack for like $1.30 for 2...

I have wiring diagrams. Diodes wont do you any good, you need somethign that will break the brake voltage when you hit the turn signal. Diode only open when voltage is passed through them in reverse, and diodes also drop the voltage by about .6volt and would make your lights dim, thats if they could even be used (which they cant)
So far I got it working fine, but I dont have turn signals at the moment...I think it might be as simple as a diode in backwards...
I can assure you there is no way to do this with diodes.
If you apply power to the brake line diode its going to pass current. If you reverse it, your brake lights will never come on.
Same goes for the turn signal. The diode only blocks reverse current, which you will not find on your taillights anywhere.
If you want the wiring diagram for the cavy tell me and i'll scan it for you.
Would it be possible to just plug a Cavalier turn signal relay into my Sunbird with my current setup and make it work that way? Or can you give me pics of what you are talking about?
If I got the signal stalk from a cavalier would it plug up to my sunbird harness? I'm going to grab one the next time at the wreckers and checkanyway if I dont get an answer before I go.
I need to get this thing ready for the road soon and weve got stupid inspection things
uh i dont know what the big deal is.... plugged the right side tail light harness right in for the left side i just cut the plug off the sunbird one and the cavvy one... and wired up yellow to yellow brown to brown orange to orange and no problem from the plug of the sunbird to the wiring harness from the cav lights....
blue i just left disconnected since it was only running to the license plate from what i could tell.....
wicked
All your lights work okay? Park, brake, and turn?
lol ok well double checked it tonight.... i dont have brake light for when my lights are on... but ill figure out a way tomorrow
unless i screwed up the blue simply runs to the license plate light.... however theirs gotta be a way to rig the sunbird tail so it works right.... my blinkers work fine, my lights at night work fine but i have no outer breaklights right now.... gonna see if i cant figure it out tomorrow
wicked
im thinking for breaks i might put leds in the center panel anyone done this?
wicked
ok tyrin and 89 IM me if you guys get on my aim is futilelives see if we cant work this out... turn signals work... center panel works flawlessly jsust the corner wiring harness is different... see if we cant figure out how theyre wired....
wicked
The blue wire is brake lights, if you put it into the yellow wire (or green depending on what side your doing) you get brakes and signal but no signal when brakes are applied just like eveyone is saying. so you need a way to cut power to the blue wire when the si9gnal is on so the signal works.
well maybe separate light for the brakes? wouldnt it be easier? run to radioshack buy 4 LEDs and put one in each corner light... or get red ones and put one in each referse light? wouldnt that be neat have your reverse lights double as brakes or something like that
