I just had this happen to my TC, I was running Mtec golden bulbs and they were 55w. I talked to some toyota parts guy and He told me they don't sell just the female part of the headlight harness, that I would have to buy the entire engine harness for $1200. So I went on ebay and bought some 9006 wireharnesse I 'll let ya all know how it works out. I should have just gone HID!!!

Honestly it sounds as if it shorted inside the bulb and cause it to burn the wire until a major fuse blew or the wire was burnt past being able to conduct electricity.

If the wire is just melted, butt splice in a new socket which you can get cheap at any auto parts store (check the fuse) and be done with it.

55 watts isn't nearly enough to cause a problem. I run 55/60 PIAA's with no grief.
Usually a short or partial short is the only thing that can cause that type of problem. The filiment itself could have a problem. If you want to eliminate the bulb as the cause, take the suspect bulb and the good bulb from the other side and measure the resistance with a volt meter. The resistance should be very similar for both bulbs. if it is not, the bulb is the culprit. If it measures good, then look for a short somewhere else.
55 vs. 51 watt is only adds about an 8-9% increase in amperage. Generally the stock harnessing is designed with a lot more overhead than that. BTW, MANY store bought bulbs are 55 watt anyways, and the "actual" wattage of the bulbs will vary a bit from bulb to bulb within the same brand.
Usually, Advance Auto or NAPA for sure will be able to sell you an H4 socket with short wires.
Hope that helps,

I was looking at the plugs on the back of my H4 lights on
the box, and they lookeed a bit scortched. This was with
factory wiring and factory bulbs. I was shocked at how cheap
they looked.
I wouldn't at all be surprised to find this one issue was simply
wiring related. There is no way I'd pay $1200 for the wiring
harness, I could totally wire something by hand bor $20 and
get better results.
Rather makes me wonder if I should.

Here are headlight bulb cross references....
An H4 bulb is also referenced as a 9003 or a HB2
A 9004 also referenced as a HB1
A 9005 also referenced as a HB3
A 9006 also referenced as a HB4 (PIAA just calls it an HB)
A 9007 also referenced as a HB5
H1, H3, H7 and H11 usually reference the same

I would see if the bulb measures as defective with a voltmeter. If the bulb has a short or partial short in it, it is not unreasonable to contact Luminics directly and explain that their defective bulb roasted the harness.
If you send them the defective bulb and the receipt for the repairs AFTER speaking to someone (getting their name and referencing it in all correspondance) , I would guess you'd have a good chance at getting reimbursed.

I found this place and they have high heat resistant harness replacments, take a look.

I have this same problem with my Xb fog light. it is a bad ground. The dealership says that can only order me a new harness. something over 2600 bucks installed. They told me this cause they dont like me at all.
I would test the bulb in question on the other side to make sure that it works, then take your car to the dealership to see what they will say. Take the bulbs with you and show them what you are using, just so they know what happened. Dont put the factory blub in and expect them to do anything seeing how the factory blub wont have the char mark on it.
