Wiring diagram for 58721 LokSound 5 DCC Direct

[Jim Starbuck]

Does anyone have a diagram for 58721 LokSound 5 DCC Direct that identifies the Aux pads and a ground pad?
I want to add two additional wired 0603 LEDs to this decoder as well as an Iowa Scaled Engineering powerkeeper if possible.
I believe I’ve identified the common + as the center pad just behind the Aux 1 LED on the back side of the board.

Thanks,
Jim

Yes, I have mapped all those pads when back in February John R. send me one of those decoders to "reverse engineer" it.  I just have to make a drawing.  It is on my "to do" list  I'll see if I can do it this weekend.

That would be fantastic.
Thank you!

I just posted the decoder info in https://www.therailwire.net/forum/index.php?topic=54278.0
Adding a keep alive will be a bit difficult as there are no dedicated solder pads for either ground or the rectified positive voltage output).  The V+ is not the standard 12V "blue"' voltage but a 5.3V ESU provides for AUX outputs as positive common.  Same as in 73199 decoders.
