-  Release spring catch securing 8-pin connector -2- to connector on 
wiring to multi-function TR switch. 
-  Unclip connector to multi-function TR switch from retainer or remove 
retainer together with connector from transmission to gain better 
access to the pins in the connector. 
    
-  Pin assignment for 8 - pin connector of Multi-function (TR) switch -
