    First of all, thanks for having me. This is my first post but surely not my first time reading on the forum. Lots of good information on here. My situation is as follows: I pulled the traction battery and replaced a bad module. Upon reassembly the drivetrain will not engage. I am getting two codes. P0AE0 Hybrid Battery Negative Contactor Control Circuit High and U0111 Lost Communication with Battery Energy Control Module. Any idea what could be causing this? Does any have a picture (or can tell me) what the polarity of the modules should be starting closest to the contacts? Im pretty sure the polarity is correct because I numbered the modules all on the same side but I am second guessing myself. The car was driving before the module swap. I have spent a couple of hours searching but cant find an answer to the polarity question or really where to go. Thanks in advance for any help.

    It's hard to see if you have the orange plug in there right, much less trying to find the hole to put it in. They really put it in an awkward spot to get to.

    There is a distinct click sound that comes from the battery when you turn the car on. It's really noticeable when you have the battery exposed.
