Hi all – Trying to find the right connector to add a speaker to a DCC-ready Bowser F7 w/ a 21-pin socket. Bowser says “JST connector” but there are about a billion, and the catalog is massive. Anyone know the exact type/series of JST connector that Bowser uses for their speakers?
Thanks
Aaron
I’ve gutted many locomotives and also lots of computer devices and have gathered quite a collection of different plugs just to keep on hand for situations like yours. It seems to me that JST (Japan Solderless Treminal) is becoming a term used for any small PCB connector. I can check later but I believe it is a 2.54mm pitch. JST company makes a large variety of plugs and connectors.
I see that Bowser has a part number for the plug, shown at the top-right of this page:

Plug with wire. Fits Bowser, Atlas, Intermountain and Fox Valley main circuit boards.
They also show a pig-tail included with their sound retrofit kits. Maybe give Bowser a call or email and see if you can buy some from them?
I see MB Klein has stocked them in the past —

but are presently out.
Micromark also lists a similar plug/socket but I can’t say for sure they’re identical.

Hope that helps,
Good Luck, Ed
The plastic body of that plug on the board can be pried off leaving the two pins attached to the board. I then just solder the wires to those two pins.

If they measure 1.5mm between pins they most likely are ZH connectors.

The JST ZH series are common speaker connectors.
I buy them off eBay.
I use them on every locomotive equipped with speakers.
