Connecting Kato Unitrack switches to ESU SwitchPilotThe Kato Unitrack switches are DC operated and require the wiring shown below to be controlled by a SwitchPilot and SwitchPilot Extension combo.Unfortunately this arrangement looks like this – too much of a jumble!So I opened the decoder case and exposed the boardsAnd soldered the connections internallyThe replaced the base and covers (after making openings in the base for the wires).And this looks neat – worthy of the clean ESU Look!
