Connector

[boyler]

When inserting crimps into a connector, is there a tool to insert or do you just push it in? My crimps dont seem to be going in the full way?

Hi

You must open the locking plate (white).

Use a proper crimper so the pin don't get miss shaped.

Yes doing that have an amp superseal crimp tool, it crimps the wire part fine but the second part where it should grab the insulation doesnt seem to be getting the correct shape.

Can you put on a link for the tool?
And which connector is this for?

Sorry Holmz, it's a M400 ECU the connector is for. The tool I have is used for these crimps ( http://www.newark.com/te-connectivity-a ... ctors_None ). The tool itself looks like this ( http://www.newark.com/te-connectivity-a ... dp/19J6696 ) The jaw that is in it looks similar to what is here ( http://www.farnell.com/datasheets/65633.pdf ) I haven't got the tool with me now to take a picture for you but I will when I'm able to. Any help would be appreciated as I'm panicking and need to get this loom done as soon as possible, sorry for being such a beginner!

Post a picture of your crimp and pins.

They really do need to be neat, and fully round. It can be a tight fit if not done correctly. If the ecu is in a clean dry environment you could remove the rubber water seal which can make insertion easier.

But a proper crimp should be easy to insert into the housing. Certainly a damn sight easier than the crimps I made for mine which needed a real good shove lol.

Yea got sorted today re getting a correct crimp, however because of the poor crimps and insertion I had done the day previous there is now a crimp stuck half way in one of the ports in each connector without wire attached. So the locking plate now wont push down, so once again I'm stuck..any ideas on how to get it out?

When this has happened to me previously, depending on how deep it is stuck; try using a fairly fine scribe or some appropriately sized tie-wire (If the correct widdth is chosen, they are strong enough to push pins out while still fitting inside the front of the connector).

Good luck.

A bit of welding wire and a pliers done the trick! Locking tab went down as it should on Plug A however it's not going down on plug B, something wrong with a crimp somewhere in there obviously! oh well!

[stevieturbo]

If the pins arent pushed fully home, or if the thing bit in the middle is too bulky the locking tab wont go home.

They are great connectors when they work, it's just getting the crimps 100% is the hard bit.

As I said, if you do not need the full seal the weatherproof rubber offers, dismantle the top of the connector and remove it, it does make working with bad crimps that little bit easier.
