Transaxle Connector Layouts
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This vehicle is equipped with a new style PCM. This is a 50-pin control module with 3 separate connectors. One connector for the engine (E), one for the transaxle (T) and one for the body (B). The pin numbers listed throughout these pinpoint tests will have the letter E, T and B to designate the connector.
