I just received my first mod kit, the 510 Box mod Kit to be exact. I won't be having any problems soldering this kit together, but the instructions state to solder one end of red wire to inside of the 510 sealed gold connector, which is part F in the pic. Problem is I don't see any obvious connection point to solder to, or an area to make a mechanical connection prior to soldering.
Any tips appreciated!
