I tried installing some aftermarket headlights. I followed the instructions given to me, but I had to apply the instructions for driver side light to passenger side light in order for it to work. And it did, well at least the long and short beams did. The problem is that only the driver side light would turn on for the day time running lights and the not the passenger side. I have pasted the instructions. Did I do something wrong, please help.




Reason for required change: As most Catera owners know the vehicle was made in Germany, and has a close relative the Opel Omega. These lights were intended for the Omega and the wiring is slightly different.

TO THE DRIVER SIDE ASSEMBLY ONLY (L)
– NO CHANGE is needed to the passenger side assembly.

First locate the wiring that will need the change (A) the brown wire for the low beam, and (B) the gray wire for the light socket that is not used**.

Cut the brown wire (A) about 3-4” from the grounding connector, then cut the gray wire (B) about 1-1/2” from the unused light socket.

The gray wire (the end that leads to the factory socket pin) run the cut end through the fixture to the brown wire with the grounding connector. (It is also good ideal to run through the sleeve going to the low beam)

Using a split butt connector (not provided) join the brown grounding connector wire and the gray wire. Using some electrical tape, tape up the unused wire ends.

You are finished.

** The small light socket is not used on the Catera. It does not provide any additional lighting benefit or reduction. (Though it is there for those whom like doing custom lighting)

well I am guessing here but when I did my headlight swap I just did it to the drivers side only not the passenger side. So you did not follow the directions is what your saying. so undo the what you did to the passenger side and start from there.

I will try that over the weekend. Hope it works.
