Atlas O Amtrak Dash 8 Blunami 4408 upgrade

After installing a 2200 in my Amfleet cab car, I have finally decided to tackle upgrading my Atlas O Amtrak Dash 8 with a Blunami 4408. So far all I have done is remove the old electronics and installed the AC to DC buck converter, but I will also outline my project plans here.

Here's the install of the AC to DC converter, I used the old location of the rectifier to mount the new one (with some thermal paste too of course). I used one of the old main board standoffs and screws to mount down the buck converter securely and so it's got some space from the rectifier

My plans for this install go as follows:
- Lighting functions similar to the original board, so directional class lights too
- Retain smoke unit control, which I will need some help wiring up
- Retain coupler functions
- Make it run better than brand new

Here's also an outline on what I will use the functions for
HL - Front headlight
BL - Rear headlight
FX3 - Left ditch light
FX4 - Right ditch light
FX5 - Class lights (green front, red rear)
FX6 - Class lights (red front, green rear. Red emergency stop light)
FX7 - Smoke unit toggle
FX8 - Couplers trigger
