You can use a non-oem headlight ballast without error codes/reprogramming! Pics

Note; this post does not condone using those cheap $25 ebay kits for your headlights.

So this morning I was installing my new Mtech v2 angel eyes and I decided to try a little experiment. I took off the front bumper and removed a headlight to get to one of the ballasts. Thanks to this picture:



that I stole from hidplanet.com I hooked a couple of wires from the bottom of the headlight where ballast plugs in and connected them to my cheapo hid fog light kit with the built in resistor. Tada! No headlight error codes and no reprogramming!
So if a ballast goes bad and you want to replace it with a different one or if you want to upgrade to a ddm tuning hid kit, it is possible without getting a bunch of errors. I have other plans...

Do you know if you can still trigger the OEM bixenon high beam shutter with this setup? My understanding is that the OEM ballast has a trigger wire that runs to the projector.

Good Post, I hate electronics, I'll take mine to somebody who made it thru shop class.

Those Pics look like how I had my 735 lites jury rigged. They wanted like 500 bones to fix one headlamp wiring, instead I hooked it up to the other lamp with an inline fuse and presto, good to go for 2 years until the whole car retired.

That is a good point and I'm not sure. It's possible the high beam shutter wiring is run through the multi pin connector that attaches to the headlight though.

This was just a proof of concept. The plan was to buy a couple more oem ballasts, gut them, and pot some wires coming out to a standard hid ballast connector so I could run modified 55w ballasts. I ended up going with some 85122+ Philips bulbs and they provided me with enough light.
