This harness allows you to install a different MAF sensor for your application and simply plug it into the factory harness without cutting/splicing/soldering etc wires.
2004+ 5 to 5 wire (Series III) - This is for a 2004+ Grand Prix to a LQ4 MAF sensor conversion. This will use the LQ4 MAF sensors internal IAT sensor like the OEM MAF.
2004+ 5 to 3 wire (Series III) - This is for a 2004+ Grand Prix to a LT1 MAF conversion. This will eliminate your IAT sensor, when doing this you will get a code. The LT1 MAF does not have an integrated IAT sensor like the factory 04+ GP MAF does. The MAF Adapter with IAT Plug is a better option, click here. This is recommended for turbo kits.
If you have a Series II car and want to eliminate your factory IAT sensor to use the internal one in a LQ4 MAF sensor, you will want this harness instead.
