Need 2002 MAF pin-out !

The stock 2000 MAF have a 3 pin connector and the IAT sensor mounted to the side of the airbridge have a 2 pin connector. Looking at the 2000 documentation this is the pin-out:

MAF:
A YEL MAF Signal
B BLK/WHT Ground
C PNK +12V

IAT:
A PPL Ground
B TAN IAT Signal

Now I will install a 2002 MAF with a integrated IAT sensor. This new MAF/IAT have a 5-pin connector and I need to know the pin-out:

2002 MAF/IAT:
A ?
B ?
C ?
D ?
E ?

Anyone with a 2002 shop manual who could scan the page from the Engine electrical section and email me or maybe fax +46 8 6231856 ?

Your help would be greatly appreciated. Thanks.

:cheers:

There is an adapter available so you don't have to splice, or in case you
want to go back, that is what I used.
Got it from PaceParts.com
Then I changed the MAF table to the Z06 values with LS1 Edit.

Thanks ! :cheers:

I've been offline until now so I just read your posts. I will hook up the new MAF today. Wish me luck :)

I got a cable with a 5 pin connector with the new MAF but no 3pin/2pin connectors in the other end. I will need to cut the old cable but I do not plan to go back to the old MAF :D

Thanks.

:cheers:

I just received the below info taken from the GM tech documentation. Please note that pin A and B differs from what nevrenuf wrote:

What are you asking? That is directly from the 2001+ service manual...and...you killed two birds with one stone, because the Delphi P/N is also listed.

You do know there are plug-n-play harnesses (off the shelf) to convert to a 5 wire MAF, right?

Looks like amazon has the connector you want:

I do, I wanted to approach a cleaner install rather than an adapter harness.
