m-txd/rxd wire (white) ecu to instruments communication

I received the proper connector and terminals, but they are a lot smaller than the Honda factory crimp tool could accommodate (their smallest size is 1.25 mm), so the improper crimping prevented the terminals from going far enough into the connector block.  So the meter assembly didn't work properly, possibly because there was improper contact.  Or something else is at fault. 

So I ordered another connector block that had pre-installed connectors with wires attached, and will try that as a last resort.  These new multi-pin connectors would mean I need to get a new crimp tool, and the tiny terminals, and not inclined to do that quite yet.
