Wiring / Wire Routing /PO work / Curious / ??

[SteveW]

Greetings -

I've always wondered about some of my coach's wiring from the previous owners work - and my recent toll window replacement project has the drivers
side panel removed - exposing two circuits that really puzzle me.

First one : 12V and ground from the house fuse panel. 12V runs from a 5 amp fuse (labeled lights) to another fuse (big - 10 maybe 20 amp) - then to
a switch - and then to energize a relay for big Bosch driving lights. I've removed those driving lights... The relay was properly wired to provide
power to the lights from the battery. The origination of the wiring seems to be factory installed as it runs through the insulation of the panel
behind the driver and through the drivers side arm rest panel... Why might someone wire things up this way ?? I'm curious because the electronic
work (lots more of it) seems well thought out and cleanly installed.

Second one : Another 12V and ground circuit from the house fuse panel traveling up to the engine compartment via the drivers side. I haven't yet
chased its origin or destination - but it looks factory installed. Can anyone call out a factory installed circuit from the house fuse panel to the
engine compartment ??

Neither of these are large gauge cables for the battery combining booster and they both appear smaller gauge than the wiring to the battery isolator.

And... One of the circuits travels through a hole at the bottom of the drivers footwell. Is that "factory" ??

As always, thank you all for the wealth of information and experience shared here.

There is a second solenoid in the rear compartment which the boost switch energizes along with the on under the hood, and there >should< be a heavy ()
or so) cable between the two. It ncarries starter current when the boost switch is energized. At least on the two 76s I've owned. A 73 MAY be
different, follow the diagram for it.

Steve,

A 73-23 is about as strange as it gets. Though they were completely documented, there are many attributes and features that are different than any
other. I don't recognize the described wires. As for through the drivers foot well, I recall no wires, but there were some hoses whose purpose I do
not recall.

Thanks Johnny, Thanks Matt.

I'll do some further exploring when I visit the coach at storage this weekend.

Based on my experience with my early '74 the answer is YES.

IIRC it was for the downshift solenoid. Why they ran it the way they did was a total mystery..

Cruise control vacuum dump valve.. the valve is mounted next to the brake light switch.
