Basic trailer wiring for a guy that's definitely not smarter then a 5th Grader.

I didn't mention that the problem when I combined the turn signal and
brake lights was that it stopped the turn signals from flashing in
the bus. Perhaps that is what the diode is for? Any ways I am
missing some piece of the puzzle. I have the extra bulbs already in
the lenses so I am pretty much commited to that method. There is
something different in the bus over a newer car. The Toad is set up
correctly. If I was towing the car behind the Tahoe I'd be good to
go the problem is in the bus, something is different. I know this is
difficult to figure without being there, but I appreciate the effort.
I may just have to get "professional help" on this one. But the
diode may be what I need. What does the diode do? Keeps the current
from flowing back? Maybe a diode on each of the turnsignal and brake
lights is what is needed? I am close here I think if I can just get
that last piece of the puzzle to fit. Help some one. I hate to give
up and call "uncle".

Instead of trying to figure out the seperate brake and signal
situation on the sub, I just used brake lights bulbs for all inputs
from coach. used diodes on all three wires. Four wire left & right
signals and brake lamps yellow and green.and the brown the running
lights. I elimated one brown wire from sub. White ground So all input
from coach go to only brake bulb no add bulbs. brown 1 input from sub
one from coach to combined running out to tail lights..
