I have an 18315 Rectifier with TMCC. It makes the uncouple sound if you press the coupler buttons, but does not have the coil couplers, just the magnetic ones. I want to add the coil couplers for TMCC control.
Looking at the diagrams I can find, I believe the coupler "hot" wires are driven by this 2 prong socket shown in the picture with the yellow arrow. This should drive both couplers, one prong for each, with the other end of the wire from the coupler grounded as I understand it.
Is this correct? Any other things to watch out for? Thanks.
