Ultimate Wiring Pinout



Is the center connector required to run MS3Pro ULTIMATE?

No, but why leave nearly half of your available inputs and outputs on the table?  At MINIMUM, pin #23 of the MS3Pro ULTIMATE must be connected to 12V+ battery power.  See pinout for I/O possibilities with the center harness.
