Howdy! I'm in the process of retrofitting some unknown lights into my 97 SC. The light kit was purchased by the CL member that previously owned the car, so I'm not sure which ones they are. I decided to put them in over the weekend, but I'm not sure which one of these wires is pos or neg... Any suggestions?

This is what I've got.



Thanks in advance for your help!

Oh yeah, and for my SC wiring harness, I've got a white/black and a white/green - Anyone know off the top of their head which one of those is which?

Thanks!

do you happen to know the brand. some ballasts have reverse polarity protection.

All I did was hooked up a ballast to a 12v source and if it doesn't turn on, i switch it and it works.

I haven't had a problem doing that. Then again, I've used mostly OEM-brand ballasts that may have a polarity protection on it already.

 

I actually figured it out the easy way... I seem to have this trend to have a tough time with the easiest things, and as soon as I actually post to ask y'all, I remember there's a ridiculously easy way to do it.

I just tested continuity between the body of the ballast and each wire. Continuity = Ground wire.

But thanks anyway - Mods please delete so I don't look like a complete tool for the rest of history!

Those are bosch ballast. Most likely they came from e46 3 series.

Yellow wire is positive, Brown is Negative.
