Default Need proper 3 to 5 wire harness for 85mm maf swap






I'm installing a Corvette 85mm maf, Delphi 25328057 in the place of my Ls1 3 wire 75mm.


I need a proper harness for the maf in the picture. I looked at the Casper harnesses but kind of don't look like the same pattern inside.

The second pic is a 3 wire to 5 wire harness that I bought and doesn't work with the 85mm maf.

Could someone point me In the right direction on the proper harness I need? Thanks

It should be Caspers Part# 108100. That is the one I purchased from Colorado Speed (one of the site sponsors) several years back and it works fine.

I need to know for certain that this plug will fit my maf.

I have looked at the one you specified and other Caspers adaptors and the plug does not look the exact same as my maf in the pic. Can anyone help?

That's the Caspers plug. It looks like the plug will fit on the pins but it doesn't have the square part that fits into the plug. Is that even necessary?

So i just took a look at mine and snapped a few pics.

You should have your maf 3 pin connector (will go in the larger black plug white top) and the Idle Air Temp 2 pin connector will go in the smaller black plug/white top, and the Green 5 pin will go into the MAF.

Hey I appreciate it. It's hard to judge the size of that maf plug inlet. I ordered that Caspers plug today. Thanks
