55 ton 3 truck shay

Has anyone got information on installing a dcc decoder into this engine?
Wiring diagram G824X-IS008 shows the track /  motor connections ok.
I can move them to the decoder.
Then it shows the wires in a 6 pin connector.
My guess is that I cut the front and rear light wires and connect them to the decoder.

Then what?  B+ and smoke unit and cab light.
Can the smoke unit be left as is and run by manual switch?

I guess I can always trace the cab light wires and reroute them to the decoder.

Any suggestions would be welcome.

Thanks,
David

Hope you get some good tips on your project, I'll be wiring my Shay soon. Did you look at IS007 also?

Yes.  IS007. Is the the analog wiring only.

I have the decoder installed.  The hard part was finding space to
put the decoder.

the 4 main decoder wires (2 track & 2 motor) just need to be
removed from the terminal block and attached to the decoder.
I needed to lengthen these wires.
this gives you control of the motor

then cut  the blue b+ common, yellow rear led+ and white front +
wires from the 6 pin connector.  attach them to your decoder.
this gives the decoder control of the front / rear lights

the 6 pin connecter can be pluged back in with the 2 purple and
brown smoke unit / cab light wires.
this leaves the cab light and smoke unit as originally installed.

Are we talking the 20.3 Spectrum? I have one, for just over a year, with DCC and sound installed.
So how hard is it to replace the decoder? Where is it ?I think its in the tender.
This is so embarrasing, I put AC to the track, the loco shot off backward faster than it ever did; now the loco goes the direction it wants, sometimes herky-jerky, making any sounds it wants. Little if any control with the control buttons.
I called CS, they have yet to call me back.

All ideas welcome.
Thanks

Never mind. I contacted Customer Service. They are going to repair my mistake, for just $50.00. Gotta love great service. The decoder from Sounstraxx is $119.
Shipping was $30 to Philly, so Im still ahead $39.00 and I dont have to tear into the tender, and show how bad my soldering skills are.
