How do I get the wires out of this connector? Special tool required? I've poked and prodded, but haven't applied much force as I don't want to booger things up too badly.




Thanks.

Seriously, you might be able to release the little spring-catches that hold the contacts in using a thin stainless dental probe.

Thanks, Dave . . . I don't have a dental probe, so I've been trying to release the catches with a jeweler's screwdriver. You don't happen to know the best way to approach the catches, do you?

There is a tool to remove those connections, but I don't know anything about it.

Look at www.molex.com

It may have a tool to help.

In the past, I've used dental type tools to pull the pins.
I've also used the jewelers screwdriver method as well.

Well, I don't have one of those connectors to look at(or do I?) but usually there is a hole, or rather a slot midway along one long edge of the opening in the mating end of the connector. A larger example can be seen on the relay board, pics on my Bzzzzt page. On your connector they seem to be along the center rib. Ideally, you want a strong, thin tool with a very gentle curve near the tip. The tool should fit down into that extra slot without binding, so you have room to work. There is a tiny tab on each metal connector that snaps into the plastic, and you need to push that tab back to "unsnap" the metal connector while gently pulling the wire out the back of the connector.

You should not have to pull the wire hard. You should not have to push on the metal tab very hard either. Try a back-and-forth motion pulling & releasing the wire, since the metal tab can dig into the plastic at which point it won't release even if you do hit the right spot with the tool. Be gentle, use patience, and study the empty connector holes with a magnifier under a strong light so you can see how it all goes together.

Thanks, Dave. You probably don't have one of these, but I have five -- two on the car (LH and EZ) and three in a box in the study. It's a Bosch 35-pin connector. I'll try applying a little more patience.

Mark,

I see your already hard at work!

I see you've got the retainer 'comb' out, so now it is only held in by the small metal 'flap' on the pin itself.

Dave gave a very good synopsis, so I shan't regurgitate it. Once, you get the first couple, it gets easy. Really.

Also, try inserting the screwdriver and rotating it several times - this seems to help work the flap down a bit. They are quite sturdy, you can flatten them completely, pull them out, then gently pull it back up again to re-insert, they don't break off (at least none of mine did, and I did about 60 pins in and out).

I'll post a pic of a withdrawn wire in a minute. Though I don't know if it will be terribly helpful. Hang on...

Mark,

Sorry, not able to produce adequate resolution on the camera I have handy. Do make sure you are working the correct side of the plug.

As you look at where the wire is crimped, you can see that the formed and crimped section of the connector is on one side of the pin - that's the side the little retainer flap of metal is on.

Hope that's clear enough - though I fear it may not be.

Call me if you need any walking through.

Thanks, Greg. Is the drawing of the terminal below accurate? I don't see the retainer on the crimp side.



(It's from the Bosch Technical Service Parts catalog -- I'm going to hunt down a source for parts from this catalog.)

the view is of the side where the two ends of the metal that is bent meet. the lock tab is on the other side.

most newer ones have two lock tabs...

Mark,

That is what one style looks like- the other is very similar but a bit different - the receptacle end is like 4 bent loops instad of 4 flat prongs.

They fit interchangably.

There may be newer styles that I just haven't seen, as David mentions.

You should also be able to find a removal tool through any Authorized Bosch Service facility. Try the guys who do diesel FI service, if the catalog thing is unsuccessful.
