I have everything hooked up and all the ballasts do is click. The bulbs wont fire. I have the bixenon harness from retrofit source, and d2s bulbs going into the retro fit headlights. Please help. Trying to finish this so i can drink! any ideas.....

 

hmmm... hooked up right?

 

go drink, and leave this for when you have some time to go threw it and not be rushed

 

Well as usual after a few beers things become clearer. I got both ballasts and bulbs to fire and got the lights aimed, have to tweak it a little tonight when it gets dark but whatever. Now my only problem is that the ballasts shut off when I put on the highbeams. I have the pnp harness from the retrofit source and it works great, the solenoids move the sheilds, and everything else works. Now the weird part, when I pull the flasher, my high beams work, but when I throw it forward, it shuts the ballasts off. I followed the instructions per the retrofit source, and my guess is the pins are reversed on the 9007 connector, I tried to take the pins back out of the socket but couldnt get em to budge. Any input would be greatly appreciated!

Bump

 

The problem you have run into is this....with the stock headlight, when you hit the high beams, the low beams shut off. This is normal and works fine with the stock setup. Pull the stick back (flash to pass) and the low beams stay powered up which is why they are working that way. Your HID's are taking power from the low beam circuit so, hit the highs and the ballast looses power.

What you need is a diode between the low beam circuit and the high, you can add this at the headlight end of the harness. Hook it up so it allows current to flow from the high circuit to the low, it will block current from going the other way. With the lows on, current goes to the low beam circuit (natch), no power goes to the high beam side (which is what you want or you would have high beams all the time), the ballasts have power, you have light.
Switch to the highs and the diode allows power to go from the high side to the low and provide power to the ballasts, and of course operate the solenoid to activate the highs.

Hope some of this made sense

 

every cobalt does that. turn high beems on and lows go off. unless you just flash your lights, then both are on.. like he said ^^

 

Yeah, I was looking at that diode setup, I think that would be the route to go, even though the harness I purchashed from retrofit source is supposed to take care of the problem within the harness its just not doing it. DaBuzzard, thanks for the good info. Do you by any chance know what type of diode i need??? I am tryin my damnedest to figure this out, and where exactly would you wire a diode in????

 

1N4004 is the diode you are looking for, should be able to get a couple from Rat Shack for a buck or so.

Here is a quick sketch (please excuse my "Mad Paint Skillz" ) of how it needs to be put into the circuit, I have heard of people doing this right at the BCM but I have no pinouts for that unit.



Make sure the line on the diode is toward the low beam side or you will have high beams when low is selected, and no beams at all when high is selected.

Rather surprised the harness didn't come with this already, maybe they shipped the wrong one?

Good Luck, let us know how it works out

 

Well I got them running, high and low beams. I used a diode that you put right in the plug. I found it on the retrofit source. Now we will see how everything runs over the next week with all the lumps and bumps of the road. It should be fine though. Thanks again for all your help, I can always turn to this forum if I need help!
