P4 Position Install and troubleshooting

Installed my P4 board in my PP Sit Down over the weekend. No problems with the installation and functionality, with the exception of having to swap out the original wheel encoder opto board with the new one provided along with the P4 board. I noted that observation in earlier posts in this thread, so no surprise there and was anticipating swapping the OG out. New opto board works perfect with the OG Atari game board. Love the ability to adjust the screen horizontal and vertical positioning in the sub menu. Great product and looking forward to any audio updates (especially for PP2) or any other updates when they surface.
Just got a P4 board to install for a friend. His cockpit wiring in hacked and having to rewire all new edge connectors. Just took multimeter to P4 board to confirm wiring and as front pcb is number 1-22, my front video is S-A. Can any on confirm this for me?
Thanks

sfspanky could you post pic of yours connected in your sit down cab?

I am on the road and away from my machine. I'm sure @ArcadeJason or others can jump here and post photos but the parts side of the P4 is facing towards the back door in a sit down. If in a stand up, the parts side would be facing the right wall. In either scenario, you are looking at he back side of the P4 board when installed in a cage. In the photo you posted, flip the board over to the right and that is what you would be looking at when feeding it into the cage. Parts side away from you and pin 1 at the top.
