Micra 160SR new owner

I am a proud owner of this little gem, had to have a new clutch put in and now I have code P1706 PNP (neutral position switch) come up the car is a 5sp manual. I think my mechanic has forgot to plug it back in where abouts is it on the gearbox can I get to it through the engine bay or do I need to get to it underneath the car.
