I recently installed the JMRI Decoder Pro on my laptop.  The problem is that doesn't seem to be able to read "decoder type" on "new loco" screen.  It times out after about 3 minutes with a "Error code 302" "programmer busy".

Even when I select the proper decoder and attempt to program the decoder it does the same thing.  

I have a bunch of Micro Engineering HO switch stands that I would like to add Txrail backsavers to.  What is the best way to modify these and attach the throw handle so it looks fairly correct and accurate?  I've seen pictures so I know that people are doing it, but there isn't enough detail to tell exactly.  Thanks.  

I have two Scale Trains SD40-2, two LokPilot 5 and two LokSound 5 decoders.  I want to replace the LokPilots with LokSounds which is easy enough except the lights won't work with the LokSounds.  They work with the LokPilots.  I tried the obvious combinations, decoder A in loco A (no lights), decoder A in loco B (no lights), decoder B in loco A, etc, etc, (no lights).  The sound and drive functions seem to work.  Is it a programming thing or two bad decoders or two bad somethings?  The decoders show manufacture dates of March '19 and April 2020.

Do any of you use some sort of plugs when you wire up DCC in your locomotives? What have you found works best (note: I'm in HO).

I'm using a DecoderBuddy Tiny in an Atlas MP15DC and both the rear (cab) headlight and the KA-4 (that I shoehorned into the cab) are permanently part of the shell - and I'd like to keep the shell fully detachable.
