Elderly neighbour asked me to swap out a ballast. No problem, not an expert, but snip some wires, marrette them, bing boom bang right?But he's switching from T12 to T8, and the wiring scheme looks nothing like the old one. Is there a way to jury-rig this, or does he need a different ballast/fixture?Pics via /r/DIY https://ift.tt/2JwTqwz
