Hi everyone,
I need some help with wiring up a replacement MAF sensor for my 03 GT2. I purchased an aftermarket MAF sensor and am trying to wire it up. I cut an old MAF sensor to use so I can plug in the wiring harnes of the sensor directly into the plug in the engine bay. Sorry, I am terrible at wiring. Your help will be most appreciated. I'm attaching some pics. Please let me know what wire goes where.
Thank you very much.

 

Why not buy a new Bosch MAF? =best in my opinion.

 

Exactly my thoughts as well.

 

I need a blow through MAF.
I have already burnt 2 Boschs and went the blow throug route. Individual intakes in wheel well.
I would really appreciate the help.

 

Based on the wiring diagram posted (which doesn't match 100% to your OEM plug)....

Blue -> Brown/White (pos 3)
Both green and black -> Ground in engine bay.
Yellow -> Violet/Red (pos 4)
Gray -> White/Blue (pos 5)
Red -> Brown/Red/Blue (pos 2) (Verify with meter this is +12v switched with ignition)

 

Thank you for that. Much appreciated.

Do you happen to have the right wiring diagram for an 03 GT2? Or the link to it?

 

No sorry I don't... was looking for them this morning to verify but couldn't find any.

 

There was a thread with the MAF pin out but the link on there was no good anymore. Shucks
