[Elecraft] Upgrading K3 --- order of installation

[Ian White]

Removing the left side panel also makes it much easier to confirm that
the connectors at the rear left of the KRX3 have been mated correctly.
First-time assembly can be a little tricky, but becomes much easier
after the connector pins have settled into their correct alignment.
 
(The same is also true of the front-panel connectors, by the way.)
