Motronic Wiring Guidance
Good Evening,
I'm working on a 914-6 project, swapping in a. 3.2L engine. Currently sorting out the wiring. A difference I've noticed from other pictures and schematics online is the connector that seems be related to the ignition switch (yellow wire?), tach terminal 2 (Black/Violet?) and , Tach terminal 1 (Black wire). My connector appears to have 4-pins (see below picture of connector with red dot)  Any insights on the additional pin - or have I misidentified this connector?

The extra black wire is for the factory alarm system.
Pin1 is the yellow wire that runs to the starter term 50 Pin 2 black/purple to the tach, rpm signal Pin 3 black to tach, upshift light Pin 4, black to alarm control unit, provides power from the alarm unit to the DME relay terminal 86, can use a switched 12v source if eliminating the alarm. Todd
