Lights out- and blinkers, wipers, flashers

Well after installing a Blue Seas ACR to isolate my house batteries on my 2004 Sprinter, I musta been a bad boy along the way somewheres;
Now I am without headlights blinkers flashers and wipers!
All fuses in steering column and underneath the seat check out fine, and I also tested all the relays and they are fine.
I would appreciate wisdom from any of you that have some bright ideas! 💡💡💡

Coincidental failure of the multifunction switch?

Since i just created it for another thread, here's a one-page-holds-all schematic of the turn signal system:



... plucked/assembled from the pages of the 2003 service manual.
You can download a 2006 manual (same as yours for this issue) here: http://diysprinter.co.uk/reference/2006-VA-SM.pdf
Section 8W is the wiring, sub-sections 8W-50 through 8W-54 cover the lights.

added: did you check the fuses in the on-battery power distribution block???

Yep- I did check all the PDC fuses and they're all fine.
I will dive into the Steering column/Multifunction switch next- Thanks autostaretx. Any suggestions on how to test the switch?
