Where in WIS can I find the connector layout for the front SAM?

I have warning messages in the instrument cluster about front fog lights and marker lights failure. So I check under the car and see they all disconnected. Probably because the previous owner installed updated headlights and a bumper cover with LED fogs. Figure I could just wire in some LED converter things for the fogs and plug in some marker bulbs to stuff behind the bumper. Just to get the warning messages off. Well, I first check to see if there is even power at the connectors when the fog lights or markers are switched on, but no. None of the 4 light connectors have power. Even when commanded on from a scan tool. Grounds are fine though. The wiring diagrams below show no intermediate connectors, fuses or relays between the fog E5/1 E5/2 and marker lights E6/1 E6/2 so I want to check for power right at the SAM connectors MR5 MR6 and MR9. Can anyone point me to a page on WIS that shows the connector arraignment on the SAM?

In the WIS under
54 Electrical system, equipment and instruments
21 Control units / basic modules
there's a bunch of docs titled
"Wiring diagram of front SAM control unit with fuse and relay module (N10/1)"
Are they any help to you?
