What is "start/stop external control" on GMT4 standalone installation manual?

0 votes
I'm installing a GMT4 into a 2013 express van using the standalone option (connection c) in the instruction manual.  The yellow/black wire says it is supposed to connect to the "start/stop external control".  The wire diagrams from wirecolor.com do not reference this wire. What is it referring to?  Also, is a hood pin or valet switch required for the unit to to work?  Last, does the evo-all unit require programming if I'm using the FLU2 to enable option 15?  If so, what is the purpose of this programming?

A pulse to this wire will make the car start, used for special application. If you are using 3x lock it is not used
