Help With Identifying An Electrical Connector

  1. Evening all.

    The bikeTrac module on one of my bikes has failed so I have had to get myself a new one. This however, is turning out to be a bit more involved.

    The new Bike Trac unit/transmitter has arrived along with a small cable which converts the old connection on my existing unit, to the new unit. Unfortunately, after locating the unit on the bike (which took forever!) I am unable to connect the new unit, because the small cable which was included will not connect to the old unit.

    The white connector on the image below which is on the cable that was sent to me differs from the existing plug. Upon investigation you can see that the guides inside the plugs are different. One is off-set, the other is in-line. I have requested the correct conversion piece with the correct plug on it but have no idea when or if it will arrive anytime soon. So, I thought I would try and tract down the correct connector and creat one myself. If anything it will keep me entertained for a while.

    I Basicall need to replace the white connector with the red one. It looks like removing the red connector from the existing unit will just wreck it, so rather than screw it up I thought I'd have a go at making/altering the adaptor myself. There is no markings on either connector so wondered if anyone can point me in the right direction!!

    Muchas Grazias...

    I've just noticed that the connector has K-A H JST marked on it so that might help me. Me eyes are getting old, missed that completely!

  2. Hi, looks like a JST connector, the catalogue is available for their range, google JST, the terminals look similar so if you lucky you can release them, usually a pin type tool to be able to pull the pin out or possibly push the tab down under the terminal, there are you tube vids about. Hope it helps.

  3. Couldn't unpick it unfortuately, good call though. I've ground off the tabs and it works, but it's really playing with my OCD. Think I just need to install the new wiring and splice it in where the original was spliced. I dare not look to see how it was done though!! :)
     
  4. @ResB1299, if you get stuck, pretty sure I have the correct adaptor lead for your unit. A large, red, 3 pin female socket as in your picture to a small white oblong, male 4 pin plug ? Bit late in the day to photograph it now but can do tomorrow. Andy

  5. The JST website is maybe worth a look. You can contact them through it. They can also tell you the tooling you need, which is usually quite cheap. I don’t know how responsive they are though.

  6. I am pretty sure you can find a pick tool online (Amazon do a few) to de-pin the connector and swap it over. Takes 2 mins.

  7. Looking at the white connector the pin retaining tabs appear to be visible below the pin. A small flat blade screwdriver could be used to push the retainer downwards and the pin removed from the back.
