Direct: Just load to the closest vias, but make sure to leave enough slack for the drive to move down without tearing the tetrode wire. Also try to make sure the tetrode wire sits under the EIB rather than looping out. It can help to *very gently* pull on the tetrode where it exits the shuttle tube to make sure it has a kink that directs it under the EIB. It is pretty easy to not see a tetrode wire that sticks out during lowering so its best to avoid any possibility of accidentally ripping them with the screwdriver.
Electrodes are typically gold-plated after the shield is attached and the drive has been almost completed. The last step after gold-plating is to secure the gold pins with a layer of epoxy.
Ground wire
Attach the uninsulated shield wire to the EIB with gold pins and/or solder. The wire only needs to be long enough to make good contact with the shield cone later.
