Wiring colours fairly generic for most early Raymarine/Raytheon GPS chartplotters.
Ebay Chinese GPS normally come complete with instruction sheet about which colours to connect to what for GPS signal.
Usually only two wires carry NMEA.
Usually takes few seconds for plotter to aquire signal on first start up.
If no signal, in the past did purchase a Ebay mushroom, which gave problems, seller resolutely insisted there was nothing wrong with it and only reluctantly refunded when a different unit purchased elsewhere worked perfectly.

If you are using an NMEA 0183 GPS receiver you connect the GPS white to the power/data cable white. GPS black goes to the power/data green and 12v Negative. Connect the GPS 12v positive to the same switched supply as the plotter.
