FYI; the repair I did managed to break itself from vibration, I walked the guy through fixing it via text message and phone; he re-attached the jumper wire by drilling out the hole where the relay pin broke off, and used a tiny screw from an old broken phone to screw through into the 'nub' on the bottom of the relay.

That won't be necessary for most people. leave the relay on; you won't break the pin off unless you remove the relay; I use 30ga wire because i always have some on hand and it fits through the vias on the board, but you can solder to the leg of the two transistors, but you have to be very careful not to overheat them so do it quickly.

My buddy with zero soldering experience re-soldered the down jumper to the via on the edge of the board with a crude soldering pencil, so anybody can do this repair. The up is more difficult but that's usually still operational.
