A few years ago the Life Like line was acquired by Walthers, and it appears that Walther's has discontinued production of this model. More recently Micro-Trains released a model of the SW1500 which is using a very similar mechanism to the one used on the Life Like models.
I wanted to see if this new decoder would also work on one of my Life Like SW8's that had not yet received a decoder.
To do this I made a set of 4 shims as shown in this photo. The shims are shown here with a ruler as a size comparison.
If you are up to trying to solder wires to these then this could be programmed for a rotary beacon or mapped to function F0 in the reverse to add a headlight on the back of the cab.
