Emax

If you want to change the connector as opposed to hard wiring it, this
connector would work:

3M Mfr part #
929852-01-07-10  14 pin Double row, gold plated .100

Mouser.com part # 517-852-01-07   $1.76

These are not expensive and are gold, so you don't need to look at tin
plated...

Or just solder the display, as Jammie has said.
The nice thing is the pins do exactly match up with the panel.

FYI- I might try putting these in or similar on one of mine just to see the
process / how it works out.

Regards,
Ted
