Old question,m I'm finally getting around to:

OK, I have two lights, two switches, both lights are on the same fuse.
It looks like both junction boxes have other circuits running off them,
which I think is the same fuse.

Plan is to run three way wire between the two lights white/red to
socket, blacks connected. Then run two way wire to the 1st switch white
(black tape) to red (socket) black to black. Then run three way wire
bewtween the two 3 way switches (white wire taped).

But I'm not sure if it matters which socket I run the switch to, since
they both have other circuits running off them. Can't I just run my
other circuits off the black/white in either junction box as it is now?
This is where it gets a little confusing.

TIA

Leave all the existing wiring the way it is. Run three wires between the
two switches. At one switch location disconnect and tape the existing
wires that were on the switch. Disconnect and tape the two wires that
were on that switch's light. At the first switch location you can remove
the existing single pole switch and now wire both three way switches to
control that one light. Last, you need to run a two wire cable from one
light to the second

OK, this is the same as the end run wiring diagrams I've seen. This makes
sense, since you're switching the circuit as opposed to the individual
lights. The problem is that I don't have access to the wiring and I would
have to drill about 10 joists to use your method. I was hoping to use the
existing two wire cable between the lights to pull the new 3 wire cable
between the lights. So is there some reason I can't use the original
method other than it simply won't work?

Thanks.

The two wire cable will be stapled at each end, and the holes drilled
through 10 joists probably won't be straight and clear enough to use the
cable as a pull wire
