You might like to have a look at the schematics on the web site below -
select 'Spanners', 'Electrics' and 'Schematics' then click on the circuit(s)
you want to see.
In your case it sounds like classic bad ground problems on the
passenger-side rear light cluster as far as the blinkers and backup lights
go. For the brake lights it looks like a disconnection in the green/purple
between the brake light switch and the 4-way connector near the RHS rear
light cluster. Either that or there are two different faults one affecting
one side and one the other, which is always a possibility.

Subject: brake light problem
> Hello again,
> The brake lights on my 74 b won't work. Here's what I've found thus far:
> The taillamps will come on when the headlights are on.
> The drivers side blinker will work, but the passenger side backup light
> blinks along with it. In fact, this backup light comes on when the
> headlights are flipped on.
> The passenger blinker won't flash, but the light will come on.
> I ran a continuity test on the brake light switch and it is working. I've
