Ok it's probably in here somewhere but question, i have a distribution module(brake lines plumbed to it) on the passenger side half way back of the vehicle. It has a plug on top and one on the front both face the front of the vehicle. Both my plugs are unplugged.
What is it? I'm assuming it is something like the esc or something but not sure. Any help would be appreciated.

 

Maybe ACE valve body? See attached..

 

Yup that's what it is, everything else has been deleted so i guess that's why it's unplugged! Thanks again.
