Here are some threads that may help in relation to:
1. WHY you should use a relay harness or upgrade your wiring
2. What PnP HID kits and other higher wattage aftermarket bulbs can do
3. If your car's symptoms match these, this could be your culprit.

The Multifunction switch is the switch inside your steering column that controls your headlights, foglights, turn signals, etc. and operates off a large pin gray connector. Many symptoms can be displayed that would relate to a fried switch or melted connector. These threads have multitudes of information on this subject.

There are plenty more threads on this....if anyone else comes across any feel free to post them and I will add them to this list.

This should save about 4 or 5 redundant threads a week :clap:

It should, it people check the stickies, plus it's nice to have all of the information in one place.

I don't think people realize how much stuff is ran through the MFS. Then when people add higher wattage halogen bulbs (ie: 85w Nokyo), or splice power for guages into existing wires, etc... it can add up quick. Adding HID's (especially in both the fogs & heads) adds some serious draw/ load on the system.

I won't sell a set of HID's with out a relay harness is for exactly this reason. A relay harness will take power directly from the battery for the ballasts instad of being drawn through the MFS harness.

Upgrading your interior & extrior lighting to Led's like Wiggyx & myself now offer will also reduce the load being placed on he crappy MFS thus helping to avoid these problems all together. I hate diagnosing & fixing electrical issue so I like being proactive. You know the saying, "An ounce of prevention is worth a pound of cure"!

 

[LilSparkPlug]

Absolutely, I've been running all LEDs since 2005.

Speaking of melted connectors... here's some side marker sockets that were melted with halogen bulbs in them. I had to replace them with new sockets & add LED's which have ran much cooler & less load.

Off topic, but where can I purchase these LED's?

And can we just go ahead and rename it the malfunction switch?

 

[wiggy]

You can order them through John (ND4SPD) or I :thumbsup:

 

[LilSparkPlug]

What's the output of those like in the housing? I like those. I have sidemarker sockets all over the place, I save them for times like those :rofl:

 

[wiggy]

Dunno, never tried 'em. I know John's rocking them. I'll toss a set in later today and see for myself.

 

[boostedneonsrt4]

Hmmm I used to run with my fogs on all the time when I had my headlights on, and it fried my connector and the multifunction switch. Sad thing is everything was stock. I am about to switch all of my lighting over to led. I have the repair kit for my connector, but it's such a pita to solder when you have so little room and not much slack in the wires.

 

[LilSparkPlug]

Yeah let me know how they look. Every LED I've put in there always ends up looking like a speck for some reason :rofl:

There really isn't a great PnP led forthe sodemarkers. It's mainly because of the shallow design which doesn't allow much room for the light to reflect. Some led strips or amcustom board about he only way to get the entire sidemarker to fully illuminate.

 

[LilSparkPlug]

I had tried that, getting these things apart is a bitch (I have one apart already) and finding a strip that fits in them is even harder since it's such a shallow mount. I'll finish them eventually. I have 11ty billion other projects to do first. Or at least it seems that way.

side marker problem

im having this problem with my connectors i changed one side and still nothing the other side is melted bout still works i have hids headlights and fogs can somebody send me a link so i can get what i need to solve this headache

 

[STV3]

Is there anywhere else i can get the wiring harness that plugs into the mfs other than the dealer? I need another new one. This will be my 3rd one. This time i have a relay for my hid's, stock fog bulbs, leds in my hvac and soon to have leds for my cluster as well. Hoping this will be the last time this pos melts

 

[LilSparkPlug]

Other than the dealer you'd have to source one out in the junkyard and hope it isn't fried.

 

[evo77]

Anyone see issues with using butt connectors for the repair kit?

My soldering skills are pretty shitty and I'd just end up screwing it all up anyway.

 

[LilSparkPlug]

As long as you connect them good and tight I see no issues.

 

[Legoman]

you should better ask someone who can solder!
