Wire Harness Build

I am trying to retrofit a TCU for my truck to get wifi, remote access to it. No one make the wire harness anymore, so I need to make my own. I bought the WPT-242 and the other end, but I need constant power, Ground, and HS3 + & HS3-.

Does anyone have a wiring diagram? Truck is in the signature.
