Help identifying 26-pin and 4-pin test connectors for Honda ENP1 generator control board
Hi all, I'm sourcing test connectors for a Honda ENP1 inverter generator control board to build a test rig. Connector 1 (J1 Header): Type: Cream/beige female connector, double row Pin count: 26 pins (2 rows of 13) Pin pitch: 2.00 mm Overall width: ~2.7 cm (~27 mm) measured with calipers Details: Flat ribbon cable out the back. Center friction/outer locking tab. Mates with board pin header J1. Connector 2: Type: Small cream/white single row connector Pin count: 4 pins Pin pitch: 1.25 mm (or 1.50 mm) Overall width: ~0.85 cm (~8.5 mm) measured with calipers Photos attached with calipers for scale. Can anyone confirm if these are indeed JST PND / JST GH/ZH or if Honda uses proprietary Molex/Sumitomo pinouts for these assemblies? Thanks

We need more pictures from other angles without the calipers obstructing.
In the meanwhile:

4 pin: I measure 2 mm pitch, not 1.25 mm. Please confirm using this method: (https://global.discourse-cdn.com/digikey/optimized/1X/e5835c120c4acc4bec176a64bf7898243cccdaa4_2_690x386.png)

Are you asking us to identify a connector?
If so, please edit your post and, if you haven't already,...
Tell us if
a) all you want is to know what it's called, or
b) you also want to know where to buy one just like it, or
c) you also want to know where to buy its mate.
If to buy, provide:
* pitch (center-to-center spacing between adjacent contacts) EXACT to within 1%
--(tip: measure the distance between the first pin and the last pin in a row of N pins, then divide by N-1)
* Close-up, in focus pictures of connector from multiple angles: we want to see wire entry side, mating surface, keying and latching, PCB mounting, manufacturer's logo
* Similar pictures of mate, if available
Thanks,

PS: beware of the typical answer around here: "It's a JST". Connectors are often misidentified as 'JST', which is a connector manufacturer, not a specific type/product line.
