Nice project! Mine still in pieces and I am currently in need of new bearings and tires.
the "triangle piece" is the neutral sensor. The oil pressure is taken from the sensor at the bottom of the crank case under the stator cover. Bottom/middle of the foto.follow them under the oil pressure sensor (triangle piece with the 3 screws in it)

I would leave the neutral light if anything its a good thing to have
