13/14 Select shift handle wiring

[Twinturbo Ranger]

I'm doing a 6R80 swap on a older car and I'm using the 11/12 shifter. I like the 13/14 handle better so I'm going to swap handles. It also has select shift and I want it to function so I'm wiring it to my controller. There's only three wires coming from the handle but I'm not sure what's what. I tried a meter to see if I could figure it out but that was a no go. I was hoping someone here might know ?
Thanks Mike

White is shift up and brown is shift down and black is your ground.

Up shift and down shift get pinned into the PCM. The signal return wire get's spliced into an existing pin. I can get you the Pin#'s tomorrow if you don't have them. You'll also have to program the car with a 13-14 strategy to use select shift

Thanks for the offer, but I just needed to know what they actually were to be able to use it with my controller.
Thanks Mike
