Just make sure that if you have more than one feeder to the reverse loop, ALL of them connect AFTER the PSX. Just one feeder wire that gets missed and is connected to the main power bus before the PSX will cause one of those serious headscratcher moments as you try to figure out why the darn thing works when a train enters the loop but shorts every time it tries to leave, or vice-versa.

Look at your bus wire run from the booster to the reverse section. Now cut it and install a PSX somewhere between the booster and the reverse section. Doesn't really matter where you cut it. Go with what will be the most convenient for you. Just don't run light gauge feeders 30 feet from the psx to the track, Stick with 14 ga until you get close.
