Installing new PCB
Just purchased a PCB from club shop for A4.
Comparing this to the original on place I can probably work through refitting and soldering wire but there seems (to me) to be two odd points.
The first is that the replacement comes with a black wire fitted but I cannot see where it attaches. I suspect answer is fairly obvious but can anyone help please? (and suggest anything else to take into account)

The black wire connects the left rail to the loco chassis. This connection is exclusively needed to feed the wiper contact which controls the 2 indicator lamps.
If the black wire connection is missing but the relay-PCB is OK, the loco can be operated except for the indicator lamps.
