The plug is on the bottom frame towards the back of the engine.
When seperated it has a wedge (green I think) pull the wedge out and your wires will be free and will thread through.
best to right down the position of each couler wire before pulling the wedge.
Now you have an answer I can only hope I got the question.
As Tich advised, the Deutsch block connector is under the rear of the frame rail. Disconnecting that should give you enough play to pull the module free of the cam cover.
If you want to remove it, then make a note of which wire goes where on the connector, use needle nose pliers to remove the locking wedge, then carefully hold back (with a pin or other pointy object) the plastic clip that holds each crimped wire end in place, while gently pulling the wire toward the back of the connector. Once all the wires are free of their clips, you should be able to pull the seal, with all the wires, out the back of the connector.
To reinstall, push the seal and wires back into the connector (in the correct orientation), then push each wire in turn until you hear the retaining clip snick into place. Once they're all in, replace the central locking wedge.
