Check to make sure your ground straps are still clean and connected between the block and firewall.

Get yourself to a junkyard and pack yourself a light lunch while you're at it. Take a leisurely stroll through the junk that closely resembles the one you need parts for. Go to the closest wiring harness to the headlight assembly, take your time and don't go trying to **** it, and unplug it from the bulbs up front. Make a simple and straight forward swap and do take the time to stop and smell the junkers, it's quite relaxing! Then, you should seriously make sure your new wiring harness is properly grounded (!), which I suspect to have been a contribing factor to your problem of overheating the bulb socket. Do take the time to go over the stuff that should be grounded and make it so. Th e job is quite simple and well worth you taking the time to do it yourself.

Did you replace the relay for the day time running lights which for some dumb reason is mounted under the front bumper? Climb under and look straight up and you should see it...mine was mounted in about the center (on the frame in front of the radiator. Sounds similar to an issue I had and it cleared up once I replaced the part...had to get from dealer still.
