LS1 to LS3 and LS7 Card Style MAF Mass Airflow Adapter Harness

This is a new MAF adapter harness to allow you to use an LS3, LS7 style Mass Airflow sensor with your LS1 harness (that has separate IAT and MAF connectors). Typically, this would be used with ’98-02 F-Body (Camaro and Firebird). You can use the built-in IAT in the new MAF or continue to use your original IAT. If you have any questions, feel free to ask. p/n WLS021
