GPS won't be detected by FC

Brought the GPS from here (same shop for flight computer): Ublox NEO-M8N GPS with compass - Unmanned Tech UK FPV Shop

The gps has a steady green light with a occasionally flashing blue light (blue light is about 1 sec between flashes)

Flight computer doesn’t seem to detect gps. Parameters are correct (for me they look right based on various other posts I found on this forum, and some guides I found). I think I simply put the wrong wire in the wrong place, and don’t understand which one goes where. Could someone help me a bit with this issue?

Or is it another error that means the GPS won’t conenct to my FC that I missed…?

Sorry for bad english. Bit late for me as I usually hit bed earlyish (gmt + 2)

What FC?

Figured it out on my own by now but took an hour of headscratching
