2-6-0 mogul decoder install

[dlb]

I have a mogul #81494 (dcc ready) that a friend has asked me to put a decoder in.
He does not have the paper work.  Does anyone know where I can get the wiring diagram?
The set on the Bachmann site is out of date and does not show dcc ready.
Also has anyone put a decoder into this mogul.  My guess it would have to be a small one.
Not much room available.  The type and/ or amperage would be helpfully.

Any NmRA standard decoder should be fine,  My mogul draws 1/4 amp running light, and a half amp starting up.  With 5 Jackson & Sharp passenger cars on flat and level track it draws just over 3/4 Amp.  Go higher if grades are involved
