I posted an unanswered request for help on this so this may be the first DIY for it.
Bring plenty of patience patience.
Take the door panel off - this is easy
Cut out a hole on the door panel with the speaker cut out template. Be sure the speaker will have clearance with the metal structure behind the door panel.
Check the fit
It fits, screw it to the panel with the grill clip interface
Install the grill
Run the wires from the door to the cabin using the existing wire harness splash shield running between the door and the car
Remove the screw at the bottom of the connector splash cover, open the connector by pulling out the connector bail at one end of the connector
note bail open at bottom of connector (passenger side)
Look for open holes in the connector to run speaker wires through
Disconnect the wire harness clips in the door, pull the splash guard sealing end through the hole square hole in the door to access and peel back the rubber shield around the wire harness in the door. Use screwdrivers to open a passage between the rubber water shield and plastic shrink tube over the factory harness. Push speaker wires into the gap and through the splash guard tube.
Smash the end of the other speaker wire flat with pliers to make it easier to pull later
