i need some help here. I did a TMCC install and I was very careful when prepping all connections. I finished up and thought I would try it before putting the shell back on. It seems I cannot program it and here is a short video of what I get when powering it up.

Are the cab lights connected to the number 7 terminal, with the ground connected to the number 6 terminal? Do any of the other lights function?
Looks like the cab lights are connected to the feature output.
How about explaining exactly what parts you used, is this an ERR Cruise Commander and RailSounds Commander?
I just used the the AC/DC commander. You are correct that I used the feature output for the interior light. According to the Commander manual it can be done. I have doubled checked all connections to make sure there isn’t anything plugged in where it should be. The last board I installed I had to use a diode somewhere should I have done the same here?
You have to program the commander for a Diesel with cab light and the lights will stop blinking. You must have programmed it for a strobe. Follow the instructions in the file below, the cab light code is AUX1/6.
Why the steam sound in a diesel chassis?
Really good question Chuck, I was concentrating on the blinking lights and didn't even notice the steam sounds! 
That is not the module I am using. That is for another install. I knew I must have missed a step and I did. I am out of town right now but I will let you all know later what happens. There is not enough room for the older diesel RS board I have so it will be installed in a freight car. Thanks for all the help again.
He may not have the antenna hooked up. You can't program it if it does not get TMCC signal.

When you're asking for help, it would be nice to actually illustrate the item that you're actually asking about. Why would you ask about one item and post shots of something totally different?
I was able to program the loco for a cab light but when the switch was set in the run position, the locomotive cab light went on when reporting up the track. I could not turn it off and the locomotive would not run. I tried conventional mode and it did not run either. Is it possible I have a bad DC commander. The couplers fired but nothing else worked. Any more suggestions?
I found out that there was nothing wrong with my install. It was a bad radio board.
I had a bad radio board that came with a Cruise Commander I installed earlier this year. When programmed as a diesel the headlamp would not turn off when changing directions. Verified the issue by swapping in a R4LC from a different locomotive. ERR sent me a replacement board free of charge. Things happen but ERR is good about correcting manufacturing errors.
Yes that is what they are having me do. I really was not expecting for them to give me such great customer service. Usually with any sort of technology problem the want to keep you trouble shooting as long as possible. We have some great companies in our hobby and they make life a little easier.
