I may have bitten off too much to chew. Looking at many Slave units and their wiring more specifically the pigtail tether that connects to the Slave board to the master board. It would seem that the tethers may be board/ loco specific. Tell ya why. The tether contains 10 wires 6 of which are 28 gauge wire and 4 of the 10 wires are 22 gauge These 22 gauge wires are for control of the motors in the slave loco. They include the yellow and white that come from the motor harness in the master loco and a Red and Black which are slave board ground and power. Looking at four DIFFERENT Slave board Tethers these four wires occupy different pin positions on all four tethers. Photos of two of these tethers below. Can someone please tell me that these tethers are not board/loco specific. Note that on the top photo yellow is in pin 9 and white is pin 10. Where in the bottom photo yellow is in pin 3 and white is in pin 4. The little tabs that hold the pins in place can be lifted and the pins/wires can be removed and repositioned in the plug if I knew which order the board needed. Also note I am not completely sure which end of the plug MTH chooses to call pin 1 you can see from the plug which end the plug manufacturer calls pin one but I am not sure that is a guarantee that MTH choose to follow that labeling. Another question I have is, In the background of photo 2 you can see logic gates would this give MTH the ability to scramble the pin order in the board to make each Slave board and tether LOCO SPECIFIC ? I also did a pin to pin trace between the two connectors and the 4th photo shows pins that are connected . j pulling my pigtails out !
