Moon Doggy: I beg to differ somewhat about the clarity of the serial data buffer directions 3rd Rail has supplied... While those directions picture what appears to be a K-Line locomotive install, most of us buyers are doing Lionel conversions which do not have the "J3" MB connections pictured. In fact, my install on a 38053 Mohawk has no tether wires of the colors demonstrated in the photos provided. The instructions are not clear as to whether the data buffer is installed "in-line" in one data wire or across a pair of wires.
Another hazard in the instructions is mentioning you may have to solder wires to the R2LC MB connections; it mentions PIN numbers, but how many people know how those pins are numbered? I have to look that information up every time I need to figure that out.
I've done many CC conversions and not had this actual issue with those conversions as the serial data connection was already handled by the ERR product and supplied cables.
