That's the one. I just used a jumper, with no problems. Others have stuck a 5K resistor in the line due to paranoia about potential transients or shorts when plugging / unplugging a trigger input. I attached my wire not to the Q1 collector but to the top of the board at the nearest resistor connected directly to the collector (schematics are at home, so I don't know which resistor). I then cable tied the extra wire to one of the bundles going to the jack. > Which side would the collector of Q1 be? The collector pin can be deciphered from the schematic. The lead that connects perpendicularly to the vertical line in the transistor symbol is usually drawn from the left, and is the BASE. The lead that emanates from the vertical line at an angle with an arrowhead is the EMITTER. The other lead emanating at an angle without any arrow is the COLLECTOR.
