I have one AFM that has a 5 male pin connector, with no idle adjust screw and one with a 7 male pin connector that does have an idle adjust screw. The female connector in my engine wiring harness has only 5 female pins. The numbers stamped on the 7-pin connector are 39,36,6,9,8,7,27.
I assume these are the wire numbers, but it won't run on my 5 pin plug. I thought it came off my '82 NA parts car that went to the z graveyard. Anyone have any ideas? Insides look just like my '83 NA 5 pin.

 

Are the in & out diameters the same? The na should be smaller than the turbo.




Holy hell! That looked smaller on J's page!

 

I started something i cant answer tonight. I left the other afm at the office tonight, so i cant compare them, but it did fit in my afm boots, so it must be a non turbo, since a bigger diameter opening would not have fit. But the 7 pin connector puzzles me and i wanted to use it since it had the idle adjustment screw.
PS yes J's pic was a bit smaller,but it helped me see the difference.
