The best way in my opinion is to use a decoder that replaces the
existing board. I just completed two SD70M's. One using a Digitrax
DH150A, while the other has a NCE DA-SR installed. I did this to compare
them. All connections were soldered, and the Athearn bulbs were replaced
with 1.5 volt Miniatronics bulbs. I have the ditch lights wired to flash
on the NCE unit which turned out great.
I have only a few locomotives that I have installed decoders in and I
was trying to come up with a way to install the resistors for the 1.5
volt bulbs and locate them so they would not cause problems. I finally
decided to mount them directly on the decoder which worked very well.
This allowed me to isolate them from other components and make sure they
do not touch anything.
My choice is the NCE DA-SR since the locomotive runs smoother than the
one using Digitrax. I should say that they were programed using the
standard speed table and I may be able to make the Digitrax match it I
guess. The NCE unit is sold as the silent running series decoder. As it
turns both run without motor noise but the NCE equipped unit seems to
run smoother. I hope this helps.
