Question OBD connector contacts

Hi,

I'm looking for help. I'm trying to find some OBD connecter contacts for a 1996 Volvo 940. I've browsed through over 500 contacts on Digi-key and rs-online trying to find something, the closest contacts I've found as JAE Electronics MX5-B-SG-C2-5000. Having ordered these, they're a loose fit but they lock-in and the male obd pin doesn't fit.

Does anyone know where I can find these connector contacts? Or are they obsolete?





Any help hunting these down would be appreciated.

Kind Regards,


Chooch

A Volvo dealership's parts person should be able to find them....in paper based parts' books, connectors were listed.

Look closely at the connector.

'96 ? ? ?

That was not the standard interface for OBD in 1996 . . . in the US for 1996.

Cut the connector off and install the then/now connector. Might need a wiring diagram.

The contacts have the locking fin on the wrong side, I'll have a look to see if I can get another picture elsewhere, the image might be inverted.

Just to clarify, I'm UK based and we had 940's sold to us until 1998, so we did have OBD II ports, whether they worked with generic OBD II readers at that time is a different story.

Thank you for your help so far!

OBD and OBD-II have specific meanings...

EOBD - The European on-board diagnostics (EOBD) regulations are the European equivalent of OBD-II, and apply to all passenger cars of category M1 (with no more than 8 passenger seats and a Gross Vehicle Weight rating of 2500 kg or less) first registered within EU member states since January 1, 2001 for petrol (gasoline) engined cars and since January 1, 2004 for diesel engined cars.[13]

So, goto a Volvo dealership in UK, and let the parts person find the right connector.

I had some other "OBD" contacts which I didn't try before. After chopping off one of the locking tabs to make it look like the existing ones, I managed to get it to work. See https://uk.rs-online.com/web/p/crimp-contacts/7122056/ for part.

Thank you for the help.

The connector states Volvo, the contact will not have anything stamped in it. Either way I've sorted it.

After seeing your post, I was browsing the parts catalogue for 94-98 940's up and down but neither the OBD connector itself or the terminals are anywhere to be found in there, which is weird.
I even tried to look it up in the 850 parts catalogue because I thought they must be using the same connector, but same story.

Anyway, glad you found a solution.

I suspect yours is a OBD-II version....check out these connectors: 150 Series Metri-Pack tangless female terminals

I ordered some of these a few weeks ago https://uk.farnell.com/amp-te-connec...2293342?st=obd

Never tried them before due to the offset of the hole for the pin, gave it a go after trimming one of the locating fins of as seen below.

It locked in place using the locking tab and the slide lock.

The pins in the OBD has enough give to make make contact and allow the connector to seat home.

Ok. Glad you got it. We're they spread, or corroded?

I'd be interested to see a pic of the entire connector. Also, it sometimes takes a magnifying glass to identify the type of marking, but there may be some type of marking on the connector, Bosch, AMP, etc. I've been trained to find that marking and then look for the part number for the terminals in my J-38125 manual.

I was looking to add CAN Hi & Low to pins 6 and 14, the Haltech Elite allows me to use a generic reader if I want to.

I've put the centre trim back together now, if I have the trim out at some point in the future I'll get a magnifying glass and take look.

I see. Yeah, terminals 6 and 14 would need to be added for the high speed CAN bus. As far as what brand connector Volvo used there and which terminals you can stuff in there, I have no idea.

Thanks for posting back.

95-98 940 models use an OBD-II connector in the bottom of the armrest compartment and they removed the diagnostic unit in the engine bay.
I don't think any US -95 940's have that connector?
However the protocol is not OBD-II as it can't be read with the usual OBD-II readers.
As far as I've read, Volvo used a different (or pre) version of the protocol.
I've seen a guide to a DIY reader for these cars on the UK Volvo forums somewhere.
