I don’t know if this’ll help or not, but on some of my “ normal 3 rail “ engines, a buddy of mine showed me a trick to run a jumper wire from the pilot truck back to the commons....helps a lot with some stubborn offenders,.....in your case, you’d still need to flip the pilot wheels around to get the best connection,...I just looked through my junk, I’m clean out of scale pilot wheels,...or I would have offered them up,...sorry,...I just drilled and tapped the top of the pilot truck itself for a 4-40 screw, and used a small wire eye and routed the wire up into the frame,....
