Re: Two wire T&T w/ three wire relay box
Very simple. You'll need to look in the parts book at a later 2 wire set up. Get the 2 relay sockets (they'll come all wired) and 2 relays. One socket & wiring will be with the blue wire, one with the green. No big deal once you have the 2 sockets in hand.
You'll discard the solenoid and some other existing stuff in the box but you'll need the terminal strip.
