I bought the SFX004 a couple of years ago and decided to try it out this past weekend. It is compatable with the Digitrax DH165 series decoder. I installed a DH165L0 on a P2k SD60 and programmed it with JMRI. I went to install the soundbug and realized it can be installed 3 different ways. It's and 8 pin connector with no number 1 pin indicator. The manual said the 165 decoder should be marked for which side the soundbug goes and was not. I checked Digitrax and their picture was vague and the diagram didn't match my set up. I checked Google Images and found a picture that did not match Digitrax. I went with the picture. To make a long story short, I tried programming the soundbug and never got a response from the locomotive. I then tried all 3 possible ways the soundbug could be installed and got nothing. JMRI would "read" the program on the soundbug but would not "write" the program to the locomotive. I even tried to reset to address 03 and start over numerous times and nothing. The locomotive runs great but no sound.
The instruction sheet shows where pin 1 is. The picture here shows how it attached to various DH165 decoders: http://www.digitrax.com/tsd/KB296/sfx004-installation-instructions/
The screws are important - the two terminals the screws go into are the power to the SOundbug.

Thanks Randy, I must have missed the screws some how. I'm going to check when I get home today.
I don't have any screws. There was not any screws in the OEM decoder and only one screw that holds the 8 pin female connector for the mobile decoder. There isn't any screw hole either, I'm going to try to find a P2K parts diagram.Digitrax pictures do not match my loco at all.
There's only onw picture in the manual and it's of a different loco that uses a DH165A0 board. It's the pictorial that shows how it attaches to a DH165L0.
The SOundbug came with two screws. You need those to attach it. Instruction sheet says thay are 2-56 x 1/4"
My soundbug did not come with screws. I found some screws that worked. And I got both decoders installed and programmed. Took it to the layout and fired it up, had sound, lights and movement and 3 seconds later had sparks, fire, smoke and smell. Fried both decoders, re-installed OE mobile decoder and the locomotive ran, it didn't get toasted. I feel like Wylie Coyote after trying to get the Roadrunner. Back to the drawing board, I doubt Digitrax will warranty the smoked decoders.
