That's not a Barco original wire. Someone modded that set. IS it a Runco? They did stuff like that all the time.

One end of this wire should be led out from the metal component of the fan

Hu,
Right between those two rear fans, there is a small PCB board (with a white J5 connector on it). On the backside of that PCB board, you'll find the connectors for the fans. You can't really reach them, you'll have to remove the metal plate first.
Check your mail for pictures, it seems I reached my max. upload limit here.

The red-black wire seems to be a wire testing 12V

The socket of this wire can exactly match with the two sockets on the baseplate board....I don't know if I can connect them like this or no connect?

Yes, it is ok to plug the fan connector in there.
The 12V trigger is meant to control an electrical projection screen. Barco on, the screen automatically rolls down in his memory position.
Only later designed Barco's had that.
