Well here's what I came up with. I went out and started playing around because if I don't figure it out...I won't be able to sleep. So here's the deal. drivers side works fine, nothing on the passenger side. so i plugged in the passenger side ballast to the driver side factory harness. works fine. so its not the passenger side bulb or the ballast.
i know the drivers side ballast works, so i hooked up the ballast to the passenger side factory harness. nothing. hmmmmm. not getting power to the harness maybe? i found that hard to believe, so i plugged in a halogen bulb and it worked fine. got out the meter and i'm getting 12 volts. Here's what I think is happening. I had PIAA bulbs in it at one time and the passenger side was dimmer then the drivers side. Turns out i fried the factory harness. so i went over to auto zone and bought a replacement (non OEM) came home, spliced it in and it worked fine. I don't think the aftermarket harness and the harness from the ballast are making contact. They're an off size and I think it's causing a contact issue. The drivers side with the factory harness and the HID plug work perfect. Fit tight as a glove. The passenger side isn't even close. I guess I'll head to the Ford garage Monday and see if I can get an OEM harness for the headlight. that sounds expensive. sh**! lol.....any brilliant ideas?
