So after satisfying myself that I got all the connections right (thanks @GGG and @gunrunnerjohn) I taught myself how to properly build a wiring harness that I could use at the auxiliary tender shell connector. It's a 10 pin Hirose connector that allows the electronics mounted in the tender shell to be disconnected when reviving the shell.
It was not easy manipulating those tiny terminals and figuring out how to use the crimper properly, but after ruining a couple dozen terminals, I finally got the hang of it and built myself a harness worthy of the MTH factory!
I also had to rig up a mount for the smoke unit since the package of stuff I got from the auction for this engineering sample didn't include it. As fortune would have it, they DID include two extra "seat" brackets that the engineer and fireman sit on. They worked perfectly (almost too perfectly) as a smoke mount after a little epoxy work:
Also had to build a custom tach mount since the pittman motor I got from Lionel didn't have the plastic mounting ring.
So finally after triple checking everything, and mounting and plugging in all the boiler electronics, I hooked up to my track power Molex connector and stood back and... Success! Video below.
The Diesel sounds are a remnant of the E9 that I stole the board from, and predictably the incorrect sound file meant no chuffing smoke. But that'll be fixed with the correct file when I find someone local with a programming track.
Thanks to you guys I now have a fully functioning gorgeous PS2 loco from the MTH archives. All that's left is to finish applying the brass adornments. We decided not to paint, the flat gray and brass look is just too unique.
One final question: I didn't have enough connections from the MUX to hook up the number board lights. Can I run a third bulb from the same circuit that runs the firebox and cab lights? Can the board handle the current of three bulbs?
Thanks again guys!
