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

[jim riordan]

I have a 2007 suburban, they wired the truck in a complicated way. Instead of trying to figure out the seperate brake and signal situation on the sub, I just usedbrake lights bulbs for all inputs from coach. used diodes on all three wires. Four wire left & right signalsand brake lamps yellow and green.and the brownthe 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..

Boys, I got a problem. I've got my toad wired up for flat towing.
The car is done correctly because I pulled it up behind my Tahoe and
had the wife run thru the lights and everything works great when its
plugged into the Tahoe. I put extra lights in the lenses with double
filaments in the bulbs Its a basic four wire connection. One ground,
one running lights and one each for the turn signals and brakes.

Here is what I have correct. The running lights to the brown lead
I can get the turn signals to work as long as I don't hook up the
brake lights. I can get the brake lights to work if I don't have the
turn signals wired in. When I go to wire the turn signals and the
brakes to the common lead (according to the directions) I seem to be
having problems. This bus has separate lights
for the brakes and turn
signals. The top light is turn signal only the lower light is brakes
only and they all come on when the head lights are on (I assume there
are two filament bulbs in each light) one is wired to the running
lights and the other is to either the brake light or the turn signal
depending on whether its an upper or lower light.

I have isolated a hot wire off of each turn signal, a hot wire off of
the running lights and a hot wire for the brake lights. How do I
wire the brake lights into the yellow and green wires which are
common leads(with the turn signals) to the toad? Maybe my problem
is I need two hot wires for the brakes one off of the right side and
one off the left side of the bus. In other words maybe I am crossing
the right side lights with the left side lights when I've been wiring
in the brakes? Maybe I answered my own question? See if you think
this is my problem and let me know. I've
worked a little too long on
this and I'm brain dead today.

Confused? I sure am. Thanks
