hello everyone, im new here and i have a question. i purchased a MRC
AD520 auto reverse unit about 6 or 8 months ago. since then i have
gotten my layout ready and need to install it. i am useing the new
Prodigy Advance DCC system and i need to control a reverse loop. the
unit itself has two yellow wires and two red wires. can someone tell
me where these hook to? i have lost the directions that came with the
AD520 since i bought it. any information is greatly appreciated.
