Arduino GSM shield and soldering CTRL/D7

Hello, sorry to bother you but I was wondering if someone could point me in the right direction.

I have an early version of the Arduino GSM shield that requires me to press the power button on the shield to turn the modem on. I'm looking to solder a jumper to the CTRL/D7 pad on the reverse side of the board so the modem will turn on when the attached Arduino receives power.

My question is: If I solder one end of the jumper to the CTRL/D7 pad where should the other end of the jumper go to make this possible?
