I am installing a VDO ViewLine Onyx 4,000 RPM tach (mod# A2C53194596-S) as a remote tach in my ****pit. Engine is Beta 20 w/120A alternator and B control panel (engine installed summer 2018.) The remote tach is only about 8 inches aft of the control panel tach (on the other side of a bulkhead.) Can I get some installation (electrical connection) advice?
