[Elecraft] KBT1

[bicyclepeddlers at netzero.net]

Howdy,
Almost finished installing the KBT1 to my K1 but got
stumped on the final positive and negative connections.
Can see where each is to go but the instructions say to put the K1 on 
it's left side and solder to the RF board from the underside.  Yet 
there were no instruction to accessing the underside of the RF board.
What am I not geting?
72/73,
