I would ask the supplier for instructions.
But it looks like it would be a simple plug in between the VSS sensor and the harness, might need to wire in a 12V supply though.

I missed the bottom photo. it does look like it goes in between plug and wire doesn't need to be cut. not sure where those plugs are.

this is what i recieved from ricks, and a pdf how to calibrate it.

You unplug the oem harness from the speed sensors on the transmission. Then PnP harness connects to the oem harness and the oem speed sensor.
