5-Pin MAF into F-Body - Connector Wiring Looked, but did not find, so beeped it all out.
Delphi 85mm 5-pin MAF is used in trucks, Z06 and is the base for
SLP and the Granatelli "low cost" 85mm MAF
Delphi 76mm 3-pin MAF is used on '98-'02 F-Bodies and older
Corvettes.
Delphi 5-Pin MAF
Connector Pins, left to right, looking into inlet
(Left)
1 IAT output, to F-Body IAT harness, TAN (tan), to PCM C2 Pin 25
2 IAT reference, to F-Body IAT harness, PPL (purple), to PCM C1 Pin 57
3 MAF ground, to FBody MAF harness, BLK (black) to main ground dist.
4 MAF power (IGN), to FBody MAF harness, PNK (pink) to ENG SEN fuse
5 MAF output, to FBody MAF harness, YEL (yellow) to PCM C2 Pin 31
(Right)
'98-'02 3-pin MAF
Connector Pins, left to right, looking into inlet
(Left)
1 MAF output, to FBody MAF harness, YEL (yellow) to PCM C2 Pin 31
2 MAF ground, to FBody MAF harness, BLK (black) to main ground dist.
3 MAF power (IGN), to FBody MAF harness, PNK (pink) to ENG SEN fuse
(Right)
This info may let you wire up your own harness or use these MAFs
in other applications (my purpose for doing this was to use the truck
MAF in a "ghetto flow bench" I'm building).
