Looking for advice

[Hoontography]

G'day guys, got my hands on a 2.5L turbo diesel d22, having issues with power loss in 2nd and 3rd gear. I've bought a replacement neutral position switch/sensor but im unable to figure out which plug it is, there are two that look identical next to eachother, nowhere I look gives me the answer.

If anyone's able to lend some guidance that would be amazing
