This cable allows you to connect two controllers into one Cycle Analyst.
Details from Grin:
'Y' splitter cable that connects one CA3-WP device to run two motor controllers for dual motor ebike systems. Simply set the RShunt value in the Cycle Analyst to half the value of the controllers (so 0.5 mOhm for a Phaserunner or Baserunner) and this will show the total current of both motor controllers even if they are not split equally.
