soundtraxx decoders

[rustycoupler]

The question i have is this, the wire for the chuff sensor where does it go if your engine does not have a place for this? I have installed mrc decoders and they just work from the power used to turn the wheels.

Dear Rusty,
You can install a chuff sensor or use the voltage controlled auto-chuff.
Have fun!

The chuff sensor wire does not have to be used.  The decoder will run fine without it attached.
