I should have informed everybody in my original post that I also changed out all the stock K-Line electronics and went to EER. The newer EER components are much smaller and they left tons of room up front. With all the wiring and MARS circuit board out of the way and all I had to do was hot glue the finished cab interior into the shell.
I like your idea about illuminating the gauge faces. But, I'm not good in the field of electronics. My electronics limit was pushed just doing this EER upgrade. Even though the EER boards had a full set of instructions I still was stressed I would mess something up of burn out a new board.
I notice from the above picture and the top of the body shell that this is one of those K-Line diesels that came with motorized roof fans instead of a smoke unit. The pulley mechanism is superior to the much later Lionel geared roof fans (VL Centipede). However I just wonder if you powered this arrangement from the ERR boards and if so how you wired it up? I have one K-Line E8 A-A set where the power supply to one engine's set of fans has failed but have not got around to installing a new DC power source for the motor.
