A photo of your issue would help.  Is this what your connector looks like?  Are wires broken off to this?

Also, your Lionel item number is whack in your title and description.  Shouldn't it be 6-38939?

That's a JST-EH connector, they're readily available.  It should be pretty easy for anyone with a crimp tool to build the mating connector and harness.  Digikey has about 250,000 of the 3-pin female connectors in stock.

Yes, this is assembled in the truck assembly.  The wires that are soldered to these pins are inOK.  I need the connector with wires that plug into this connector.

Thanks,

Sounds like you need some of these:

They fit inside your connector that should look like this:

Wrong connector, the connector in the truck is a JST-EH 2.5mm connector, the pins for that JST-PH 2.0mm connector will NOT work.

Lionel lists the lead wire w/pins as 2.0 and 2.5 mm: 

LEOCO TERMINAL / 2.0 & 2.5 MM / W/BLACK WIRE - 691CN25BLK

Well, I can tell you from first hand experience using a lot of both JST-EH and JST-PH connectors, the pins do not interchange well!  Yes, you can cram the 2mm ones into a 2.5mm shell and sometimes they'll work.  Trying to cram the 2.5mm connector into the 2mm pitch shells rarely works out, they don't latch properly.

I'll renew my recommendation to use the proper terminations for the connector if you don't want endless frustration.  There's a reason that the manufacturers make contacts for each size of connector.

What's on the other end. I have the crimping tool and may be able to help. 

Thank you to everyone who responded.  A special thanks to Mr Miller who had the correct connector  and was so kind as to send me the proper connector with the needed leads attached.

We are certainly blessed to have available to us a forum populated with such helpful and generous folks!

Thanks also the OGR for providing this place for sharing our hobby with others from across the globe.

As someone who isn't an expert with electronics, these connectors have always confused me - seems like there are very subtle differences in size and shape.  I've looked at the DigiKey website and Amazon, and it's very difficult to tell if a product will fit.  I've noticed that Amazon sells assortments with a crimper tool - is this the best way to go?  Is there a particular assortment that is recommended?

I'm also not excited about ordering one from Lionel and paying $10 shipping on a $5 item when they can be bought in bulk for much less.

Don, thanks for the nice compliment. This forum certainly generates a lot of new friendships.
