    Will this adapter work to plug in a LS3 Map sensor to a LS1 harness from a 2002 Trans Am? A LS3 map is recommended on the Holley mid rise intake.

    I'm using the harness from a 5.3 Vortec that was originally in my Avalanche. Will the is adapter allow me to connect to the LS3 connection?

    Asked by: Alex1993
    This will allow you to use the LS1/LS2 MAP sensor with the LS3
