Hi , the wires I fixed were the orange, yellow and red that were hidden where you used the torque screwdriver to undo the side black plastic. In your case it is hard to see any evident usage. I would start with these wires since they are the ones that fixed the problem for my upshift. Also double-check your blue and purple wires. I am not sure if these would help but I had originally welded them.
Follow the wires through as much as you can I am certain you will find a cut in the plastic.
Good luck, let me know how it turns out.
