That almost looks like you can put the pin out of a male header and swap it out. (Something like this.) You'll want to make sure the header is long enough -- I don't know what the standard length for a male header is, but I would think a 90 degree header pin could be straightened, giving you enough length to work with.

If you pull it out "root canal style", make sure you use a ohmeter to find out where it goes to, so on reassembly you can check to see if your work is G2G. I like how compact that accelerator is.
