I want to create a pigtail for auto up/down for Crewmax rear window

A while back I bought the Autoloc module to make the rear window on my Crewmax go up/down with one touch. The reason I haven't installed it yet is because you have to cut into the factory harness and I do not want to do that if I don't have to. I would like to build a pigtail to go in between where the rear window connector goes into the rear window motor (if that makes sense). I'm looking for a little help to see if this can be done.

The connector is Q10 in this diagram.


The description says that Q10 is:


This is the connector type:


I would need to source this connector and all the necessary hardware, pins etc.
But I would also need the other end that could plug into this connector. Any ideas?

 

For reference this is what I'm trying to avoid cutting into.
