Comparison of HO-scale Wired decoders - listed from left to right - first by manufacturer, then in order of price. These decoders come with wires meant for installation by cutting and soldering to various points on your loco. These can be hard-wired to almost all HO-scale locos, S-scale locos with can motors, and some O-scale with good quality can motors. Loy's Toys offers these same decoders with the NMRA plug installed for about $4 more. As such they will fit most HO-scale and larger locos that are pre-wired with the NMRA socket. We also offer the decoders which have the JST connector with Digitrax's Athearn harness. See each decoder's page for more information about any of these options.
