Please read pages 1819-1827 (first page to be considered page #1) before proceeding. Upon reading this section you will learn how to interpret the wiring scheme.
Read pages 882 and 883 for CVT general wiring scheme.
Then read pages 901, 903 till 906 for little further insight of the system and location of the different components.
On page #2132 you can see the both connectors of the TCM and the wire color codes of the attached wires and also their usage, here you can also see the unused cavities of both connectors.
Also see page # 2133-2134, here you can see the ECM (ECU) connectors i.e., like the ECU/ECM you have got (P2J-J62). If the wire color codes matches that of yours (engine wire harness that you have recently acquired) then things are pretty much straight forward.
Now jump to page # 1927 and check it carefully up to page # 1930. Here you will find what number of wire (with color code) on a particular connector connects where. Male/female connectors, associated circuits and sensors all are given with details.
Still some detail will be missing which may not be necessary at this stage like how and where the shift indicator lights are wired and their connector details, you can find detail about them in the subsequent sections at any time.
I hope this may help you in successful wiring of the CVT (M4VA).
