Upgrading existing 14-50 outlet to Wall Connector

You can also mount the wall connector near the J-box and run a pigtail out the side or bottom and into the wall connector.
This is what I did when I replaced my 5 14-50's with wall connectors. Just put Extention boxes in with splicers, and ran the wires
over to the wall connectors. I have to say , it looks pretty nice, and if I wanted to put the 14-50's back in, nice and simple.
 
Now that I’ve downloaded the Wall Connector manual (shoulda done that before my original post), I see that the Wall Connector also supports conduit entry from the top or bottom. So, I’m considering 2 options (picture added for clarity):
  1. Remove the junction box with the 14-50 and connect the existing conduit directly to the top entry of the Wall Connector (cleanest approach), or
  2. Remove the 14-50 from the junction box and run another short conduit to the Wall Connector
The service loop in the junction box is relatively short, so… Option 1 would require placing the splicers inside the Wall Connector wire box (if allowed) or carefully shortening the conduit (with the existing wires inside) so I have a sufficient service loop. I also need to research how to properly splice wires for a 240V/50A load.

I just left what was installed for my 5 14-50 plugs. I then get an extension box, which you have already, and ran conduit over to the mounted
wall connector. Since was not easy to find studs, I screwed on plywood first onto the walls so I could screw the wall connector on
tightly. I spliced #6 cables with heavy duty splicer, and ran cable over. Works and looks great.

Is the plywood screwed into studs? If not it really isn't doing much. And most new drywall anchors support the 10# weight of the HPWC, especially since you will use at least 2.
