You're looking for:

//-----------------------------------------------
// CONFIGURABLE VARIABLES
//-----------------------------------------------

// Whether the program should look across connectors to detect rotor thrust
bool detectBlocksOverConnectors = true;

This argument is set after you load the script into the programmable block.

Load the code, check and exit. Then access the control panel and select the
"EDIT" button below "CUSTOM DATA" - you'll find it on the first line following
"configurable variables"

Dont look for it in the script before it's loaded into the Programmable Block.
