At the top of our Gen. Fan Compartment there is a 12V panel. In that panel there is marked "RH DIR" and "RH FRONT DIR (WL)", "LH DIR" and "LH FRONT DIR (WL)". The WL isolators are powered the same as the R/L DIR. What is the purpose of the WL isolators? Seems redundent but then it is a BB.
I wondered that too, found these when I was trying to figure out a way
to separate the rear turn signals from the rear brake lights. I was
not successful.

Curt, wonder if one is to the loom that goes to the trailer plug and
the other for the set that does the bus mounted lights. should be
an easy test to prove?
The front blinkers in the bus do not come on with the brakes 'the
wire to front blinker' would be a spot to trip a relay for blinker
only trailer. the brake light switch I believe is a air pressure
over electric switch on the service line???? just find the relay?
and use that signal to trip a relay.--- In

I spent an entire afternoon studying the blue prints and chasing
wiring trying to figure out a way to do it and came up with zilch.
One would think the turn signal circuit would be faily simple, but in
reality is has 8 or 10 relays and about a mile of wiring.
Take good notes, because if you figure it out, I am going to want to
know how.

Curt, if you have a electric brake controller, test that the 4 way
flashers dont bleed back to throw the brakes on and pulsate with the
flasher. the fourway flashers may be one other relay in the
mix????? here is a product to protect the bus from a ground
shorted trailer

it does what the fuse relay setup you built for my bus does except
thy need to fuse the battery input from the tug or tow vehicle(not
to be confused with 'toad'
.

Dick, I found this
link for a signal-stat controller. the front directional and rear directional are wired independent. front blinkers dont carry thestop signal .thestop signal makes its way into the appliance. you would need one more wire to the rear to carry the brake only signal. unless you have a wire for a brake controller that is not used
