    If the wiring harness is a 14 pin wiring harness, YOU DO NOT NEED ANY ADAPTER to install 2B524697.

    896542A01 is designed to connect to an EARLIER (cannon-plug style) keyswitch harness, and adapt it to a 14 pin engine.

    That should be the correct adapter for your needs... thanks for clarifying what you actually have.

    Installing a 14 pin harness for each engine would be the "simplest" method. There are a couple of possible configurations of the Smartcraft network at the console, however.

    Take pictures of what you have behind the dash or in the console... we can go from there.
