Sounds like you bought an RF chips with a drop in harness too? Where'd you get it from?
If you just get the RF chip normally it comes with the single plug and loose wires like in the vid.
It sounds like you have an aftermarket harness too, in that case look to where the wire from the solenoid plugs into the circuit board. You then unplug this, take the harness and one plug should go in the board, one plug should connect to the solenoid wire you just pulled off the board and one plug should connect to the RF chip. Then your good to go.
Hopefully that makes sense.
