Can anyone tell me how to install a decoder in a loco that is not DCC ready or possibly give me a link or two?
Thanks!

There’s information on this site for decoder instalation on an Athearn deisel locomotive

Decoder installation basics from Tony’s Train Exchange.

Information from Digitrax for specific decoder installation.

What scale ?

What locomotive ??

What decoder ???

All these questions make a difference !!!

Scale: HO
Locomotive: Bachmann 0-6-0 Saddle Tank
Decoder: Uhhh… Not sure, some $20 one somewhere!
