Hey Guys,
I just put in a set of HID's into my 99 4runner. And now my fog lights do not work.

I noticed the H4 bulbs stock are a 3 prong plug and my HID's are a 2 prong plug. So I'm missing something, but what do I need to do.

Thanks!

 

Im guessing you are talking about the Limited Fog Lights..

And on that note.... Hmm. Im not sure. I didnt think the fog lights ran on the same circuit as the head lamps so they should have interfered... But maybe the 3rd wire was a ground wire.. Try splicing it off and grounding it and seeing if the fog lights come on then.

Just a suggestion, see as I dont have the limited lights, just running off knowledge of head lamps.

Anyone else got an idea?

 

I tested the spare prong for ground with my multi meter and got nothing, I was in a hury as it was my lunch break so haven't had a chance to really dig into it.

I'm guessing the third prong completes the circuit, because the fogs turn off when the high beams are applied.

 

your right the 3rd prong does complete the circuit, because when you activate your highs the fogs cut off
