Can anyone give a newbie some tips for adding a decoder to a P2k 0-8-0 please?
All the wires are carried to the tender via a plug-and-socket, but once in the tender there's an array of electronic parts (diodes mainly) which I presume are related to the lamps. All the wires are already coded correctly for DCC, interestingly enough.
Is it safe to just install a decoder in place of the current electronics, or do I need to fiddle about more?
TIA!
1. Open tender
2. Remove shorting plug
3. Fit decoder.
4. Test, then program without tender shell
5. Fit tender shell.
6. Have a drink of your beverage of choice and run the locomotive.
(A bit more complicated with sound)

Here is a little additional info.

An installation in a Life Like tender. Not sure if is like your tender.

If it has the NMRA eight pin connector, you should be able to plug in directly.

I recently put in a Soundtraxx DSD LL080LC decoder in an 0-6-0. It is supposed to work the same as with the 0-8-0 and is advertised as plug n play. The tender is smaller so in fact it was more difficult to put in the speaker, but I did it and as this was only my 3rd install and the first that required a soldering iron, I was very proud of myself. Everything worked fine. As they say just go for it.
A word of caution though on this decoder, I can't get rid of motor hum and it turns out this decoder is an older design that doesn't have back EMF. The hum is just way it is. I was able to reduce it but I find it annoying.
Thanks, folks. I suspected it would be an easy one, but didn't want to blow a decoder finding out I was wrong!

Hmm, the tender for the USRA 0-6-0 should be the same as for the USRA 0-8-0. Both used the USRA small tender. The 4-6-2 originally was going to have the small as well, but it received the medium, as did the 4-8-2, making the Bahmann heavy Mountain's tender incorrect for as delivered.

I have the DSD-090LC and DSD-100LC with the same issue. I have replaced them with a MIcro-Tsunami. What a difference. I buy most of my DCC from Bruce at Litchfield Station. Tony's is good also.

Gene,
I guess I should have been more explicit. The only difference was the height of the coal load. The 0-8-0 has a higher coal box(?) so there isn't much room for the speaker in the 0-6-0, at least in my version. I couldn't use the speaker baffles.
