Hmm I was thinking the same thing but I just took a look and they seem to be in proper positions.

The front turbo DP has black wires for the front and rear o2 sensors.

The rear turbo DP has grey wires for the front and rear o2 sensors.

This is the way mine are setup now.

I did recently have to replace one of the o2 sensors (rear o2 front turbo DP) because the wires were frayed.

Now I'm confused
JB4 and other stuff
