I am also upgrading a K-line scale Mikado. Everything in the instructions looks simple. Then reading this thread, I am getting confused. In the cruise M instructions, the example of the K-line Allegheny had the following instructions:
“3) Locate the 10-pin connector in the kit, and plug this into the mating “J4” connector as identified below.”
”4) Locate the serial data line cluster wire nut, and attach the wire from “J4”, pin-1 to this cluster and replace the wire nut.”
The instructions doesn’t mention soldering a serial wire to the R2LC 24 pin for the K-Line. The instructions do mention that step for the Lionel examples.
early in the manual, it made the following distinction between K-Line and Lionel:
“Finally, the serial data must be connected to the Cruise “M” for speed step and setting the configuration information. This connection does not exist on Lionel locos, but does exist in K-Line cruise locos.”
I was thinking I should follow the instructions and not solder the serial wire to the 24 pin, but this discussion appears to contradict those instructions. I would like any advise before I make a mistake.
