Quick update, found another plug on ebay, contacted seller with regards to terminals. There two are two types of connector, the choice is based on cable size, two weeks before he can get them.

So I am getting some traction on this, slow it may be, but this may hold the answer?

Sorry I'm so late responding.
Get the 10 digit part number off the plug housing (***-***-**-** format) and call a local MB dealer. They can search the number in the parts catalog and find the proper terminals. You can then add your own wires. Be sure to get the wire grommets to weatherproof the connection.

I'm not working today but now I know why Andy was asking for that info.

No apologies needed mate, your help is appreciated.

The number on my plug seems to be the same as seen on every version I have seen i.e. 2205450329. A phone call to a MB dealer in Spain will be like pulling teeth, we do have a dealer about 30 odd minutes away so will visit them Monday. Depending who is at the parts counter will dictate how successful I am, as I do not have a chassis number to work from may make it difficult.

I will report back as soon as I know something, perhaps there are cable options?

Many thanks.

Dave

If you can get a part number for the small wire pins too, that would be very helpful.

A0095458126 appears to be the small connector p/n Dave, this from the same guy on ebay who told me two weeks delay for the larger connector. It does show on his site as the correct one for the Mercedes plug.

The picture is not great but, it compares well with the one I stripped out of the plug.

Two pictures, the first is the small terminal and is the same number I gave earlier, and the second is the list of terminals this guy supplies. Number 25 is the small terminal, and 250 is believed to be the larger one, incidentally the 250 is also marked as 'YPT 9.5', unsure if this reference is to the connector internal width which is also 9.5mm soooooo?

OK an update.

As anticipated the Mercedes spares department is pretty impotent without a chassis number, this is not exclusive to MB as Spain operates on numbers alone.

So, I gave the parts guy the plug and using the number he located it on the system, he was able to confirm the terminals are available without cables however, when trying to locate the terminals the computer would not proceed without a chassis number. This could be because different vehicles use different cable ratings?

So, I offered him the cable number given in the above post, this was confirmed as a legitimate number for the plug however, it is the same number used on all the the plugs, probably due to the low amperage needed by the fan controller on all models. Now, the large terminal is not logically placed alongside the number for the small terminal? There is a vague diagram on the parts computer screen which indicates that part number P 016 545 56 36 is possibly the larger terminal, it is shown supplied without cable, it was not possible to confirm this is the larger terminal without doubt due to the poor quality images on the screen.

I have ordered a set of each, they should be here Wednesday or Thursday.....or possibly sometime next week.....this is Spain afterall.

In the meantime I am hoping 'feets' can work some magic at his place of employment, perhaps confirming or correcting my findings thus far?

The connector for the 4 mm wire is 000-540-36-05.

There is one available for a 6 mm wire. It is part number 000-540-37-05. You will have to verify that it fits in the plug with the fat wire. I believe it will since the standard wire has such thick insulation.

The weather seals are 000-545-79-80 (4 mm wire) and 001-545-05-80 (4.5 to 6.2 mm wire).

Hope that helps.

For what it's worth, when I need a VIN for a car I don't have I'll look at Ebay and other online car sales to find a car that has the option I need and grab its VIN.

Nice one feets, all we need to find out what he sends me, and why the numbers I have have so little in common with yours?

I have bought high current assembled connectors and C6 PWM controllers from a member on this website. His name on here is: TRENDZ

His prices are reasonable, and he has the commercial crimping equipment to assemble the connectors and terminals.

Mark

Handy to know Mark if someone is looking for a custom setup.

Given my issue with the thinner cable seems to be an isolated one I doubt there will be a rush on the terminals 8>)

I have had plenty of help from the contributors on this thread so rather than just put new cables in, my feedback may avoid a problem fo someone in the future?

I would suggest that if someone's fan was on flat out continuosly, then their cooling may be marginal and they would investigate the cause? I do tend to test modifications quite hard, it gives me that little extra confidence and safety when off roading, in particular in the summer months.

The part numbers I listed are for the TERMINALS. Wire not included. Feel free to add your own.

Mercedes does not believe in selling terminated wires unless you're buying a full harness.

Perhaps you were dealing with either an unexperienced parts guy or one who went for a quick answer.

I've been really deep into these things over the years. When you get into wiring bits you have to know what you're doing and use some thinking outside of the parts catalog. Wire terminals are really easy to look up right up until they aren't easy. I frequently find myself having to switch car models to find what I need.

Most parts guys don't realize they have access to the technical wiring diagrams and the majority of those who do have no idea how to use it.

So right mate!

I knew it eould not be easy, to be fair it is a Mercedes franchise, plus VW plus SEAT, one parts desk 3 marques to deal with.

I will be visiting tomorrow, get back to you.

$5 for a single pin (#250 in the picture above)?

That's crazy

Is there a part number for the equivalent to 000-540-36-05 with the heaver gauge wire?

Yep! $5 per pin.

000-540-37-05 is your equivalent part number for a 6 mm wire with gasket.


The terminals crimp the gasket so you have to be specific on that.

To give you an idea how Mercedes works, I had to do a search for the part number in the catalog. When it gave me a list of cars I had to start going through each chassis to find the part and see how it was shown. Several of them showed the part with the plug and no other options. One of the chassis showed the part in a page of terminals and I was able to find the larger terminal there.

What a pain

Thanks for the part number. The cable is only $2 more than the pin itself. Makes that a no-brainer.

I was slinging parts in the body shop at a different store when this thread was started. At that place I was dealing with Mercedes, smart, Sprinter, Porsche, Jaguar, Lotus, Lexus, Volvo, Maserati, Bentley, Rolls Royce, Bugatti, and McLaren. That's a lot to keep up with and there was no good way to be 100% fluent in all of them. I am still very good with Lexus and Volvo but the other non-Daimler brands are fuzzy at best.

All of connector parts are available from Mouser Electronics...if you have the MFG part numbers really helps, as their inventory is massive.

May have already been brought up.

OK an update.

Today I was presented two packets of terminals by the MB parts guy, unfortunately both sets were small terminals.

A 009 545 81 26

This is the small terminal identical to the terminal supplied by Dave, and

A 016 545 56 26

This terminal is identical to the first number except in one area, this is where the copper of the cable is crimped, the area that crimps on to the waterproofing grommet and subsequently the cable insulation remains the same.

The plug entrance for the small terminals is large enough to take either of the small terminals, the grommet is large enough to fill the void regardless of terminal number chosen out of the small terminals.

I am trying to not leave all the footwork to feets.


I was offered pre prepared small terminals with cables (yellow) for the plug, but as I am wiring in the fan to have as minimal connectors as possible I declined them.

Next, I have ordered pairs of the numbers given by feets (thank you) terminals small, large and grommets all in next week sometime, no stock in Spain, plenty in Germany.

It will be unteresting to see the difference, I cannot see why there would at least three different numbers for what is essentially the same item?

So, watch this space 8>)
