Wanted: EZL Wiring plugs / connectors - part number?

[195910]

Hi Everyone,

1992 500E.

Very smart Bosch workshop technician broke off both plugs. these are the two large ones that connect to the can bus. Can these be ordered ? Does anyone have the part number ?

Regards

Here are the missing plugs. PO toke the car to Bosch to diagnose the ignition issue, they broke both plugs, changed the spark plugs with wrong FR8s and gave him a huge bill.

What the...! How did they break those? It's almost like it was done on purpose to access the wires for testing. Idiots!!!

Did the shop at least fix the ignition problem? Was this an official Bosch-owned shop? We don't have Bosch repair shops over here.

We don't have Bosch repair shops over here.

Yes, we do. We have Bosch-authorized repair shops, which generally display a sign or a logo on the outside of the building indicating so. Many established European car repair businesses in the US are Bosch authorized. I know tons of them. Don't know that having that authorization makes a shop any more or less competent or not.

I see the same in Europe. Pretty much EVERY shop that specializes in MB, BMW etc repair has a Bosch authorization and sign hung. Even more common over there.

He was talking about this Bosch authorization, not an actual Bosch-specialty shop where it's ONLY what they do. Though I have seen a few of those on both sides of the pond, too. Such as Jerry Fairchild Industries of Redding CA, or Pacific Fuel Injection of South San Francisco, CA. They are not exclusive Bosch shops, but that's the bulk of their business.

I meant a Bosch-branded or Bosch-specialty shop, not Bosch-authorized.

You are probably right that 195910 meant "authorized", i.e. an indy shop with Bosch banner stuck on the wall.

I thought maybe they had special stuff across the pond.

This was as Dave described a "Bosch-Service" authorized indy shop.
I have the invoice for that and it said "ignition module testing", they broke off both covers to test the signal.
They couldn't fix sh## !

You would be surprised to hear that in Europe there is a scarcity of young-timer specialists. we are talking hours drive to the closest in some cases.
Plus these technicians rarely see a V8/V12 benz let alone work on one. Our guys in Q8 are more experienced in the V8/V12.

Now what do I do about those plugs?

Now what do I do about those plugs?

I have a sneaking suspicion those particular plugs are moulded to the harness they are attached to. That is to say that they are not supposed to be broken open like that and the whole harness may need replacement VS being able to buy the plug housing separately.

I think your options are either apply sealant to make the wiring waterproof and ignore the ugly fix, OR cut off good used connectors from a junkyard car and attempt to splice them on. Since it's a sealed connector it still won't be a clean solution.

As Joe said, the "correct" fix would be to replace the entire harness (NLA, I'm sure) but that would be a nightmare.

For the record, MB has a breakout-box tool which plugs in between those round connectors and the EZL, to allow testing without destroying the connectors...

Yes and a Bosch center should have such tools which apply to various cars...they did not use any of them
