Identifying wiring connectors

[MAIK72]

I was trying to identify the japanese connectors on a spare zl400 wiring loom.
I knew that the most of the connectors are sumitomo parts.
This symbol is similar to that of a diamond lying on its side, similar to that shown. The logo could appear anywhere but the most common place is at the wire side of the housing.
But i was more confused when i found this symbol at the back side.
I couldnt zoom in even closer but there are a T and a D letters (?) inside a
rhombus .Digging a little deeper found that this was the Tokai Electric Wire company mark ,before Sumitomo change its logo and copmany name in the 80s

So i guess when you re buing new original Japanese connectors from easternbeaver, cycleterminal or elsewhere the "new" diamond logo must be present in both terminals and connectors http://www.ebay.co.uk/itm/10-x-Sumi...hash=item2598688b9f:m:mnRUDws64WeANMbSwG9ZZfA

I've never paid much attention to the symbols. When I need a certain plug I just match it up. E bay has several vendors online.

I guess there is huge difference in price and quality between the japanese connectors and the chinese vendors.

To a 3 year old chinese scooter i had to replace allmost every electrical part including regulator,alternator,lighting ,battery from bad cheap chinese connectors.
Maybe the only weak spot on the 30 year old japanese wiring is the regulator connector

Thanks for the info, one of those things you never think about until they break.

Besides the alternator to rectifier lines these connectors were built to last 3 lifetimes.They never break
