they are in this way vcc-tx-rx-gnd on APM now find the red wire on GPS which must be connected to 5v on APM and black wire of gps to gnd on APM blue to tx and green to rx if doesn't detect gps try to swap tx and rx. you can find out vcc pin by doing connectivity test.

Are the vcc and red wire different sir?

Both are the same ,On gps red wire indicates it must be connected to 5v/vcc and black wire to gnd and rest of two wires to rx and tx. In order to find VCC terminal at the GPS module port do a connectivity test with a known VCC on the board. A VCC is the middle pin of output of i.e signal-VCC-GND.
