Larry,
Well, the plan is to mount two 10 gang boxes..............one for "BAT" and
one for "IGN" Fed by the Appropriate 10 or 12 ga. wires.

It would appear that I will also have to provide for two separate fused
circuits for the "ASSY" fed by the two brown 12 Ga wires. Those may be a
simple 1 gang circuit each. Tanks for the heads up!

Tom,

I originally thought that the fuse box had two feeds to it,
the ignition feed ( hot when the key is on ) and battery feed
( always hot ).

When you posted this thread, I was looking at the fuse panel
picture from the MM and had the wiring diagram on my computer
screen.

I encountered a problem when I was rewiring my recently installed
EFI with spark control. I originally connected the ECM to the
ignition tab on the fuse box with plans to reroute permanent wiring
later.

In the past few days I was doing the permanent wiring project and
connected the ECM to the windhield washer circuit from the fuse box
and the coach wouldn't run. Referring to the fuse panel and wiring
diagram, I now learned that the instrument lamps, transmission control,
cruise control and warning lights are on the ignition circuit.
The windshield washer, heater and a/c controls and air suspension
compressor fuses are on the accessory circuit.

Connecting the ECM won't work on the accessory circuit since it does
not receive power when the start circuit on the ignition switch is
engaged.

Good luck with your project.

Isn't the backside of the factory setup also the main bulkhead connector?
