I have re-set rear VMM"s # 3 + 4 , when batteries are turned back on all lights on MUX 4, VMM work appropriately; even number 1 (left directional), Number 3 (marker Lights) and Number 6 (tail lights). Even though OUT put lights on VMM indicate that the the running lights, markers and left directional are operating from VMM output and all check good; there are no running, markers or left turn on rear of coach.
I have checked all fuses and relays in rear compartment and all appear good! Swapped relays from original positions and no difference!
Does anyone have a diagram for the wiring on the two output plugs on MUX 4 going to chassis, or know which plug has the outputs for the running lights, markers and left turn. I am starting 6to think it is wiring or plug connection from Vmm's to the light sockets.

Any thoughts or comments appreciated
