HO-Scale Intermountain U18B prior to TCS IB-MB2 and WOW121-Diesel decoder installation
In order to remove the shell, we must first remove the front and rear couplers and their housings.
With the couplers and their housings removed, the shell can be lifted up and off of the locomotives chassis.
With the shell removed, we can now unplug all the JST connections.
Next, remove the four screws securing the factory light board.
With the factory light board removed, we're left with two long screws (front) and two short screws (rear).
Additionally, we are left with a shim bracket (front), which we will reuse along with the four screws in the next step.
Next, place the TCS IB-MB2 in its mounting place and secure using the four screws and front shim.
Now you can solder the 2-Pin JST speaker connection harness to your speaker, and mount your speaker in the enclosure.
Mount the speaker behind the motherboard in the cutout in the frame (we used hot glue, but you may be able to use screws), plug the JST connectors into the IB-MB2 (according to the diagram that came with the motherboard literature), and plug-in the WOW121-Diesel decoder.
For ease of putting the locomotives shell back on, we used some kapton tape to secure the wires and keep them out of the way.
Finally, place the locomotives shell back on and reintsall the front and rear couplers and their housings.
Note: In this install, we decided to use the factory speaker and baffel.
You have now installed a TCS IB-MB2 with a built in KA2 Keep-Alive™ and WOW121-Diesel decoder into your HO-Scale Intermountain U18B.
