matters need attention.
Please note:When assembling the wiring, weld the cable and the cell correctly, connect the B- of the PCM with the total negative pole of the cell, and then insert the cable into the needle base on the PCM. (Note: different connection modes for different strings, and different connection modes for the same port)
