Aftermarket bback to OEM headlight Ballasts

carvalho360 · 12-22-2016, 12:23 PM

Tired of having headlight problems every 6 months, I'm trying to make the switch back to OEM ballasts but I did not do the original OEM to Aftermarket. Having some preswitch anxiety clearly

and need some help.

OEM: I have a ballast with pre-attached ignitor. (just one as I haven't committed fearful of the cost associated)

Aftermarket: Ballast with a relay harness i believe its called...has 2 separate plugs. One for the igniter and another with 2 plugs that run into pos/neg metal tips that connect further into a wiring harness id suppose. Sorry if that isn't clear, its too cold to take good photos with the tire off, waiting to get into my garage this weekend

If I make the switch back, is it possible the guy that made the original conversion hacked up the wiring harness that plugs into the bottom of the ballast? Does that whole setup require replacing and whats the likely cost?

Where could the original connection have been relocated to if the aftermarket kit doesn't plug directly into it...The image i attached shows the wire i cant find (not the ballast igniter one)

I hope this makes sense haha

Sorry this makes no sense to me. But, the oem harness likely is plugged into that red/black cable you see there on the ballast. With an OeM ballast the harness plugs into that directly and that short extension is eliminated. Not sure why you don't have OEM ballasts as they can power HIDs just fine, unless you went with 55w or something.

Explanation is not good enough. Need to take off the headlights and take a pic of what has been done if you want more proper feedback and suggestions.
To help you with your verbiage, visit theretrofitsource.com. You will find everything you need there including male/female harnesses that plug straight into the OEM ballast.

IN your picture you attached. The silver park that goes on to the D2S bulb is an igniter. The open ended black harness is a just a male/female harness.

As mentioned, actual pics of the previously done work would be helpful. Good luck.
