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.

3 to 5 wire (series II) - This is for the typical Series II to LQ4 MAF sensor conversion. Most common for Northstar throttle body conversions. This will allow you to either use your factory IAT sensor or the IAT sensor in the LQ4 MAF.
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.
