two different packages apparently. got the actual headlight switch, from advanceauto. says brs or something on the box but when you open it it is an actual ford switch. too bad that was not the problem. waiting for the wiper switch cluster thing.

My 91 GT had same problem. Only flash to pass. It was the Multi Function Switch. Replaced it with a 20 dollar used one and it never gave me a bit of trouble....

got the new multifunction switch finally ( well used actually). plugged it in and everything works! unplugged it right away though. one of the harnesses that attaches to it is melted. i have read about the fog light problem and fix for these cars but am not sure that it is the fog light harness that is cooking. anyone have a pic of which harness to the multifunction switch does what?

The feed wire from the headlight switch to the MF switch (IIRC, red/yellow on early aero foxes) often melts or backs out of the connector. This wire is not used for flash to pass.

thats what i thought, yet all the "headlight/foglight repair kits don't include that exact wire plug. it is the plain rectangular one with those wires you posted. the repair kits are just the "fog light" plugs and wires. anyone know a source for a this replacement plug or at least a part number?

Same harness connector shown burnt half way down this thread. i am still searching but keep finding both of the other two harness connectors that hook to the multifunction switch but not this one...

found that one late last night, only thing i couldnt get over was it won't cross match to a mustang. but it has to be it, regardless of crossmatch or not.

The description says it fits E8ZZ-B & F0ZZ-A,B which are Mustang part number prefixes.

gotcha, figured it was. i mean how many harness parts would they make that look like that. just could not find a spot that said "mustang" next to it. regardless, its ordered and on the way. thanks!

Ive had a similar issue with the pull/ dimmer switch on my 95 mustang where the wire got so hot that it melted the plastic and i was going threw switches like crazy.

I noticed that if you cut the wire that keeps overheating and attach 6 inches of a thicker gauge wire between the factory wiring and the clip in the plastic harness that the plastic will stop overheating making a permanent fix to this issue.

Example~ Ever use a vacuum cleaner or something with a high draw for a long time and notice that the wire near the plug is warm? Well by increasing the gauge of the wire near the connection will help keep the wire from overheating. The heat from the wire transfers to the metal in the switch ruining the switch as well. That's why you'll notice that you can easily bend the pin that was heating up while the others are much stiffer.

You guys can thank me later

Chris
