OK, so, I have been working on my car for the last few days off and on, as some of you may know. I have learned a LOT, this being my first time really doing anything under the hood that isn't electrical (computer guy).

I've resealed the breather covers on the valve covers, replaced the spark plugs and ignition wires and the cabin air filter. I also, think I probably win the prize for the nastiest air filter (it had leaves in it... just bought this car).

So, anyway, I am missing what appears to be some sort of connector for a hose, can't find it, don't know what it looks like, and I have a wire that is unplugged that I don't know where it goes (I think it's the horn wire, as the horn hasn't worked since I bought the car). Also, the wires that connect up to the ignition switches (the black boxes), for the ignition wires themselves, the little part that holds them onto these blocks snapped as the plastic was just worn out... anyone have any solutions for this? It seems I would have to rewire the connectors onto the wires and pin it up correctly as the wires run deep back into the car...

Anyway, pictures of the first two issues on their way. Thanks a lot for the help!!

Found the rubber connector for that hose, whew! Now, that wire and any ideas on those clips that are broken for the ignition boxes... I'm thinking about maybe trying to rig them with some wire ties somehow. I just don't want them popping off!

 

To get photos that fit in the standard width of the forum page use the following method, it works a treat. It automatically resizes photos that are too big.
Here is a photo of the missing part. OK I see you have found it while I was taking the pics.
I can find no wire that matches the red wire, where does it come from?
Is it a wire that was used with HID's that have been removed?
Logically if the connection for it exists then it should lie in the radius that this wire can reach, if nothing matches it then something else is missing.
Do the rubber caps on the back of the low beam headlights have holes cut in them for wires to pass through? If so that is for the HID's which have been removed.


Here are the coil packs

 

So, there is a number on the end of this wire 968339-2 (B), a quick google query brings me to this...

Mercedes Plug Terminal Wiring Connector A 2105402081 on eBay (end time 07-Jan-11 20:12:50 GMT)

This is the female end of the wire that I have sitting out, and it's saying something about the ECU?! This concerns me... Anyone ideas, please?

 

John, thanks so much, I actually found it, sitting on the bottom of the skid plate (or whatever you call those plastic things on cars).

Any ideas on this wire?

 

So, here is my rig job for making sure that the broken connectors stay on the coil packs.

Basically what I did here was take 3 wire ties, wrapped one really tight around the top of the connector, there is a nice place for it, fits well, then strung the other two together and ran them around through the bottom of the coil pack where there is a little slit and back up to connect back to itself. It isn't the best looking thing in the world, but it def is holding them extremely well. Easy enough to replace too.

- As for the wire, I don't think it's for the lights... I thought it would be nearby as well, but I can't seem to find anything for it to fit to. The wire is wrapped around the hood latch release cable... if it's the same as yours...

EDIT: Just checked, no holes for the rubber caps. Also, the wires are kinda worn, but I think they are orange, one with a red stripe (neg, pos).

 

Can you tell where the 2 red wires come from? It looks as though it's a fairly large gauge wire.

 

Has this car had an accident at that area? My hood latch cable and the wire shown wrapped around it in your picture are neatly clipped underneath the radiator support. Both the wire and the cable disappear in front of the radiator
Is that end that you are holding the same wire that is wrapped around the latch cable? I thought it was two wires in the picture.

 

The car has been in an accident there, so, that is likely the reason for this, but I am still concerned that it's important as I don't have the full history of the repair.

It's the same wire that is wrapped around the hood latch cable, yes, that is the one... where does it go?

 

Can you post a picture of the face of the plug and pictures of where the wire is going to. It's hard to tell from the picture but from the back side, that connector looks like it could be for a multitude of things. Also, where'd you pick this car up from if you don't mind me asking.

Take care

 

Yea, let me snap a photo... I don't know where the plug is going really, it just lying behind the driver side headlight with about 3 feet of slack, partially wrapped around the hood latch cable.

The car was picked up from a guy in NC in the mountains, btw. Got a great deal on it.

Could this be for fog lights? Does the base n/a come with fog lights?

EDIT: looks like the n/a coupe base didn't come with fog lights, as mine is... not sure though, maybe the wire was still left there? I can't figure this thing out... killing me.

 

That was my first thought when I saw the back of that plug was that it was for a 9006 bulb but it's tough to know as there are other connecctors on the car that use the same back half as that but the pins and plug center are different. Do you have a multimeter? You could always probe the pins for ground continuity and then if you find that one is always grounded regardless of the state of the ignition, then test the other side for voltage when the light switch is pulled out, when the ignition is on, when the car is started etc. If it checks out that it is on with the headlights, check to see if there is another one under the passenger side headlight or inside the fender well. Perhaps the PO removed a set of factory fogs before he sold it and left the wiring in there. I'd also check the inside driver side fender as well in case that wire was just ran underneath the bumper cover and he wrapped it around something to prevent it from falling out onto the ground when the passenger side light was removed.

Good luck

 

Yea, that was my next step, I was just hoping someone could see that same wire wrapped around their hood latch cable and be able to pin-point where it's running. It goes back to the point where there is that cluster of wires that runs into that small amp, that's actually behind the plug in the pictures I took. So, it has to go to something close by. But I just don't know what.

 

No luck, it has nearly 8 volts running through it with the no input...

EDIT: I tried it with key in all the positions and lights on, as well as the light **** pulled out (I assume this is for the fog lights). It doesn't have any affect on the voltage running to the plug.

 

Where the latch cable goes through to the front of the radiator on my car a wire that is covered in black tape goes through with it. I think that it is the horn wire, but the horn wire may have two connectors on it, one for each horn.
If you do not have a wire going through then possibly the person who put the radiator in after an accident may have forgotten to thread it through first and then could not be bothered to correct it.

 

Well, the horn has two wires running to each horn right now. I thought that might be it, but I can't figure out where that wire actually goes on the horn. I felt all around the backside of the horn and everything. It just doesn't seem like there is another spot. Is there a horn control box somewhere around there that this would go to?

 

In this picture there are wires the same color as yours. The connector looks the same as well. You can go to my Engine folder in my gallery and zoom in on it. The horns are out so I guess they are horn wires shown in the picture.

 

Kinda hard to tell. Are you talking about the one hanging down? The tip looks different in that pic, looks longer...

 

You're gonna have to follow the wires back as far as you can. I know it sounds like a PITA but if it's showing 8 volts to ground and no ground connection on the other plug, something is feeding it and it's not direct battery voltage. Get me a shot from the front of the plug so I have an idea what we are working with. Take pictures along the way and report back with the results. Only way anyone here can help you identify what it is and where it's supposed to be connected.
