Ok, I have installed a PS-32 in an S-2 Bantam Turbine to replace a engine mounted PS-2 5V. Tight fit but it fit with relay facing forward.
I also installed one in the tender of a RTR 4-6-0 set with the 5V board in the tender. In this case the speaker is forward were the tender shell is tallest, so the board had to go towards the back were the shell slopes down. Had to mount the board directly to the chassis without the metal bracket provided.
Later I will be installing one in a Premier NYC Dreyfus engine, and the Unshrouded N&W J. I will try to remember to take pictures.
The current flash program in this board has headlight output with diesel characteristics. I have the new file that fixes this and have successfully installed it.
So hopefully it will be posted soon. For those that have purchased kits or are using them in upgrades, you will need the new hardware table to get the headlight correct on steam. G
