HAS 3.1 w JAMMA Extension P1B6/P2B6 issues

[greenpear]

Hello,
I was hoping to get some guidance on if it possible to address an issue related to the HAS v3.1, Jamma Extension, and Button 6.

If I have the blue kick harness connected between the HAS to a Naomi 2, I can program/use all of the buttons.
If I introduce the official Jamma Extension and connect the blue kick harness between the Extension and Naomi 2 I can program all buttons but P1B6/P2B6 are not recognized in game. This is with the default Extension DIPs set 4/5 on, 6 off.
If I switch all the DIPs on the Extension to on and still use the blue kick harness between the Extension and the Naomi 2, P1B6/P2B6 is stuck on in game.

I read a few threads talking about cutting traces on the Extension but not specifically for v3.1. Does anyone know if there is a solution for this specific issue?

Thanks

Please don't cut anything, this isn't necessary for the HAS. Can you post a picture of the harness end that connects to the PCB game? I want to see how the signal harness is oriented (it uses a 40-pin connector, but 4 pins aren't populated).

Ok, here are some pictures. The 40 pin connector is keyed so it really only goes in way.
1) Jamma end
2) HAS end
3) Jamma end

Thank you for the pictures. Rotate the signal harness 180 degrees, and everything will work. The harness SHOULD have a white/golden mark on one end - it should face the PCB game (the same goes for the power harness).

That was it, thanks lol!
