I did 2 installs of this great little decoder in some Bachmann HO scale 3 truck shays. Installed a 8 pin plug and and was able to plug into the existing Bachmann board. Very tight fit in these models once all the wire is tucked into the water tender, but it is doable. Was able to program to Westside Lumbar company Shay settings - Model now sounds excellent and performs better than they did before the install. Would highly recommend this decoder.
Probably the best and easiest sound decoder to install. Superior sound and fr at docomentation.
Relatively easy to install. Works well.
