Default 3 wire to 5 wire maf conversion?

I've been reading up on converting from a 3 wire MAF and IAT sesnor to just the 5 wire MAF with the integrated IAT sensor. Everyone seems to be using an adapter harness from Pace or someone else.

However I would like to know why not just cut the ends off the F-body harness and solder them onto the 5 wire pigtail?

Heres the outputs I found:
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)



Will this work?

The 85mm maf has the IAT built in so just rewire the IAT in the air box into the 5 pin plug, you can get a 5 wire factory MAF plug on e-bay for 6-7 bucks, the color codes are the same just match and splice in. I did it, no big deal. You will need to retune.
