I'm not familiar with this switch module but I have a feeling that I'm going to get to know more about it. I hope the pics help.You had me worried as I recently used a foam cannon with simple green to degrease my engine bay, I worried I may have messed up that module (no pressure, just foam). However, my backup camera is working fine, it's just my forward facing one that wont enable. Unless, there is some way to screw up that module and have only one camera work?
