I received a scramble cab that had the edge connector hacked off at the wiring harness. I bought an edge connector and wired it from the pinout and a couple crappy pics I could find. I sourced a pcb and it seems only the player 1 controls work. I assumed when wiring that in upright mode the 2nd player wires weren't needed since there's only 1 joystick. I wired the controls to the p1 connections and am finding only they work. Did the original harness have jumper connections to the p2 controls?? I'm at a loss other than joining the p1 and p2 like to like somehow.

Can anyone verify the right logic for controls and how they're wired for a scramble upright?

Here's the pinout.

I can get you pics from my upright harness in the next couple days.
 
Scramble is odd in that it uses P1 or P2 controls regardless of whether it's an upright or cocktail cab. I found this out when writing a high score save routine for the game and assumed it checked for upright or cocktail and only used P2 if cocktail.

I don't have an original upright but I guessed they'd commoned the P1 and P2 controls at the factory.
