I've been building a Tech Edge wideband lambda sensor convertor for use
with my Megatune - and the supplied connector for the sensor has arrived
sans terminals. Obviously I can get them from Tech Edge - but they're in
Oz and tend to take a while. It's a Bosch 7057 or 7200 Connector - pic
here.

I suppose I wouldn't have too much trouble sourcing a complete plug from a
dealer - but wondered if anyone recognises the actual terminals as a
generic? I've checked out RS with no luck. They're female and accept a
thin blade 3.5mm wide.

Looking at the page and the part which states that Bosch were forced to
continue manufacture of one of the plugs, I doubt you'll find them from
anywhere other than an automotive suppliers. Might be worth trying auto
electrical specialists though.
