Product Overview
This MDB harness will work on any Dixie Narco SIID (S2D), SIIDe, or S3D control board. This is all you need to install an MDB coin changer and validator with an SIID/S3D board. The connection on the board for this harness is already there, your 110 or 24 volt coin mech harness is probably plugged into it currently. The SIID boards are all MDB capable from the factor. It's very easy to install, takes about 3 seconds!
