At 1.2 m long, this harness connects the TRM to Powerwall 3 when wireless signals are weak, such as in meter cupboards or metal-clad rooms. Factory-terminated for the TRM side with two stripped, tinned leads for the TACO (pins 5 & 6), it ensures stable, noise-free data. Extendable up to 50 m using 0.2–1.5 mm² communication cable.
