So would c have a separate ground wire for chassis or could i combine both grounds?

Look at the 240 plug and the z32 plug. The letters will be marked on the plugs, and you just need to sodder and heatshrink them together.

3 to plug, one to chassis.

Be sure to always test wires with a Digital Multimeter for correct 12 volt/signal/ground..... Sometimes only following colors can get you screwed up, burn your MAF, ECU or wiring harness. Some people extend wires using any colors they find, either to relocate MAF's for cold air intakes or Engine swaps.

Follow the Alphabet code on the MAF, as long as you wire 12 volt to pin (E)
(D) to ECU ground
(C) to Chassis ground
and (B) the 0-5volt signal wire
you should be fine, as some N62 MAF plugs/pigtails are different colors also by users modding or repairing them.

As for testing the N62 MAF to check if its bad?

After hooking up the correct wires to the MAF, while plugged in, turn key on ACC, engine off, then Check voltage from signal wire by back probing the pin (E)..... good MAF will read .5-.4 volts, anything Higher, check wiring before starting the car. If you have the MAF off the car blow slowly and lightly into the sensor, voltage should raise.

If you do start the car, and have idle problems? Shut off the car! Unplug the MAF, restart, if it idles check your wiring, and for codes on ecu. If wiring all checks out MAF is bad but above test will tell you beforehand. Make sure also there is no UN-metered air entering the pipes behind the MAF.

Double check all wiring to make sure you don't Fry/Burn your ECU or MAF's or worst your Harness!

Symptoms of a burned ECU include, no Ignition, richness, MAF code 12 even with good MAF's, car not starting at all, ECU not having power, Fuel pump not priming, no dash lights, buzzing of the EGI relay, Blowing of any fuses, symptoms can vary depending what circuit got damaged.

Open the top cover to the ECU, look for Burned/Burnt traces, resistors, diodes, or capacitors. Any smell of burn or sweet odors is not good, and sometimes you wont be able to see/smell the damage.

At that point I suggest checking the harness for shorts also, check sensors and relays on that burnt circuit also, repair them before getting a new ECU/MAF.

Research anything your not sure of..... if you can view/find this website, you are fully capable of finding answers online. The People here are very nice compared to other places, but they will not do the work for you. Its a learning experience for all of us, for, if not for mistakes? No one would find the correct ways of doing anything!

people do a lot of different things with these wires ground wires, some people leave one ground disconnected some people connect both grounds to ECU and Chassis

I have an N60 MAF which is almost the same as N62 MAF (same shape, same plug, same wiring, lower max power)
anyway I opened it up and found out pins C and D are interconnected inside.

here is a pic

does anybody have a pic from inside of the N62 MAF?

Have a question, as I recently started some MAF wiring cleanup -
For the grounds - do the N62 ECU ground and Chassis ground HAVE to be wired that way? Any negative impact from wiring the MAF chassis ground to the ECU ground, and the MAF ECU ground to the Chassis ground?

I dont want to come off sounding like a spoiled brat or anything, ive blown up my share of mafs, made all sorts of housings to hold boost, try to tune them to feel like a stock turbo car....in the end its so much more trouble and headache than its worth...and the way the boost surges with a maf in draw through is far from ideal, and blow through...well be prepared to service that maf/replace it when you blow it up often.


Please, i beg of you all....stop using mafs...i hate them and they will discourage you when it comes to easy tuning.

Investing in a MAP based form of tuning should be your first priority before doing anything to your car.

And when you have options like MS2PNP for $700 i dont see why you should have any excuses.

No offense ment to anyone here, i just have a deep hatred for mafs.

I can't see it either. PM supa. He may have a copy of it that he can re-upload.
