My standard to prepare drives

[torikoos]

Thanks for showing us that, I've used many different ways of reducing the wire mess inside locomotives, and the test pcb board you show is still one of the better ways of doing so.
The only problem I normally struggle with to find space for are the following items:
- The keep alive capacitor on sound decoders (usually attached with a pair of wires)
-the sound decoder itself, usually needing to fit on top of a motor, in very limited space, particular on older athearn engines with thicker shells, and higher older motors.
wiring running from and to light bulbs , but the micro connectors are a good option, I just haven't found the right type yet, I have struggled ordering the correct one, and got too big a size...
