Evo 3 to 7 MAF

[evo1]

Hi all, I'm looking to install an Evo 7 MAF into the CE9A, I couldn't find any reliable info regarding the MAF plug conversion other than buying an adapter harness from the US.

Can anyone confirm if the MAF wires are a straight conversion, that is wire 1-1 through to 7-7, as per attached photo?

Thanks in advance.

I think you would need to find a pinout diagram for each and go from there?
I wouldn't rely on just swapping them straight over

Understood, thanks :thumbsup:

BTW this upgrade is being done in conjunction with 560cc injectors and Evo 7 ECU, which I know has been done to death, but I'm slowly trying to work through this upgrade myself!

So far this is what I've compiled from these and other links, and after a bit more digging I might have found the missing 'Link' and answered my own question??

I've used information from these documents to possibly confirm the straight conversion?
https://linkecu.com/documentation/EVO3+.pdf

2G TURBO MAF (Evo 1-3?)

1 - 5V Power supply
2 - Barometric pressure
3 - Air flow sensor
4 - MPI control relay (EvoLink shows +12V)
5 - Ground
6 - Intake air temperature
7 - Volume Air Flow

Evo 4-8 AFM

1 - +5V
2 - Baro
3 - AFM Signal
4 - +14V (some show +12V)
5 - Sensor Ground
6 - Ambient Temp

Hopefully this information will help others doing the same conversion, but please let me know if I have missed anything here?

Thanks again.

I can't remember, but mine is working... Also, my maf ended up with a stuffed atmosphere sensor in it, so I wired one externally.
