I’ve answered my own question after I was sent the schematic. Someone has jacklegged this wiring. They installed two push buttons as stated then cut the harness blue-black-green-red and had them spliced into only one side (ech side) the other side leading to front they just left the wires cut. I’m looking at the Pinouts now to determine which ones they cut and trying to determine why.
Newbie here to the BD world and have a few?

To add, it appears the engine off/run switch quit working and they cut the harness to wire push buttons in. Digging into it now lol
Bingo, that’s what has happened. They had electrical tape under the button so it wouldn’t make contact and using the push buttons to bypass, not sure why but they did. Maybe switch pad went out. Going to splice all back together as original and go from there

Looks like a complete re-wire is necessary unfortunately. But hey you bought it cheap. Would make it reliable.
Yep. Known issue. HDM has new improved ones available.
What does HDM stand for? Is there a way to test this keypad control board?
If you have a good print and a good ohm meter. Yes each bottom should read to ground. So fine the wire at the EHC plug then hook one lead to it and the other lead to ground. Then press the button you meter should read continuity. Sometimes it is easier with two people.
Note always disconnect the battery first before removing the EHC plug.
Look for bent pins or any pin shorter than the others.
Good luck. It took me weeks to finally get rid of my problems.

That looks pretty rough but I think we have seen worse believe it or not!
