The plug between the engine and tender on my bachmann 2-8-0 broke. I bought a 6 pin mini connector from tcs as a replacement. Can I just directly wire to a jst harness and attach the decoder? Do I need the tender board for anything? I plan on adding resistors inline for the lights. I just seems redundant if I'm remove the stock wiring harness.

All my Bachmann steamers have LED's with the resistors on the PC board. Unfortunately the resistance is quite high and makes for a dim headlight I have read in different forums over the past few years. Over 2k on a couple steamers I had.
If it were not for the resistors, all you have to do is remover the caps. The two inductors are a moot point without the caps. Some think the inductors that are green are resistors.
I worked with LC networks over the years.
Older Spectrum 2-8-0's had light bulbs. Some replace with LED's. Some like the effect of a real light bulb and put a 22 ohm, ½ watt resistor in series with one lead to protect against voltage surges which is what really shortens light bulb life.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
