unattached wire - MTH Cab Forward, 20=-3346-1, PS2- 3volt | O Gauge Railroading On Line Forum

Have a 20 gauge (blue) wire that came loose at a solder joint inside the engine, near the mux board, I checked and it is not chassis ground or center rail pickup. Attached are two photos,

Can anyone tell me where it attaches? I checked the Tech Service manual - no help. I do not see any p[lace on the mux board for it. Both the headlight and back-up

It gets connected to the boiler MUX near one of the caps. See the picture here:

It's connected to DC ground on the mux board, that's the inboard pin of the cap on the corner.
