does the N60 have the same wiring diagram to the sr harness as the N62 (z32) does and does the N60 make the engine run lean or rich?

Lean vs rich is not how MAFS affect tuning.

A MAFS just reads the volume of air entering the intake stream. But some MAFS give off different voltages of sensor info sent to the ECU, and some can read more accurately.

The ECU is programmed to read the voltage of the MAFS that it originally came with. This is why you MUST use a voltage converter like an SAFC when you change your MAFS to say a Z32 MAFS on an SR. Otherwise the SR ECU will get the voltage directly from a Z32 MAFS, and get confused and run aweful. Voltage converters get the sensor voltage from any MAFS, then convert the voltage into a number the ECU will understand and expect to make air fuel inputs.

So if you have a voltage converter and you put on a Z32 MAFS the engine will run like stock unless you change or alter the settings in the SAFC to trick the ECU into thinking there is more or less air entering the engine. Thus changing the fuel mixture.

As for wiring, its similar, if you have the harness for the MAFS then just match the wires, white on the MAFS should equal white on the harness, black to black, white/black to white/black. There is an extra black wire, ground it to the chassis. And there should be an extra wire thats green/orange on one end of the pigtail, its not used at all.

i have an SAFC. but my in puts are 4in 6out and the car runs fine. the reason i say that is because i thought the in/out was suppose to be 2in 6out. but your awesome on here, you know your stuff cause you've helped me more than once on here.

also which black wire needs to be ground to the chassis? i have one that is just black and another that is black with gray dots down it.

The black wire closer to the white wire is grounded to the chassis. The next black wire over goes to the ECU.
