I have looked and looked for hours but have come up empty handed. I am trying to wrap my head around the proper wiring to create the daisy chain that connects simp BMS module to the Tesla slaves. The instructions show the first connection and last but none in between. For the most part its no big deal to figure out but I am lost on the TX wire going between the 1st module and the each module between that and the last one in line. Is this the way its done?

Here is the wiring on the hack a day project.

I notice now there might be an problem in my drawing

Module two to module 3 should be Pin 4 or 9 on module 2 to Pin 7 or 2 on module 3.
The key to note, every signal has two pins physically connected on the boards.

That makes much more sense now! Thank you for clearing that up and sharing your diagram. I see now that all the pins are connected with their neighbor across from them and which pair is for what purpose.
