Not clear on why you are replacing the wiring --- it may not be code compliant today, but it looks like all it needed was a bond wire to be close. The "rusting black iron" was probably S-40 galvanized conduit - much less likely to leak than anything that gets installed these days. Not sure how the wires got snipped so short, but I'm glad I'm not the one trying to reconnect to that lamp cord! Trying to get a connection there that will work with an GFCI ought to be a good day's challenge for a lot of folk.

The center wire is the lamp; wire sizes depend on what else is switched or on the circuit, and also the lamp amperage (watts / volts). If I had to guess, I'd speculate that the lamp was controlled by more than one switch, in a 3-way or 4-way arrangement.

You might want to talk to an electrician who understands pool wire, pool bonding, and electrical safety in wet areas. Do a light wrong, and you'll kill somebody. If you don't get an electrician, at least run the circuit through a GFCI. That way, if the wiring is not up to snuff, you probably won't be able to keep the circuit live.

Good luck!
