Couple electrical issues Need help

[BIG ORANGE]

Bought a 71 chevy, it had sat fr a couple years. Put in a new battery, installed a new alternator that has the internal regulator,I do that on all these old trucks.
Replaced all bulbs.
Now here's where the issue comes up.
Turn on the lights and every light comes on.
Give a left turn signal bout front and rear blink.
Give a right turn signal and the front light goes out,,
and the indicator in dash dosent blink, however the rear blinks.
Push the brake pedal and the right rear stops.
I'm no electrical guru so gotta reach out.
Also the truck has door ajar switches, I put a bulb in the dome and all was fine but when I put a bulb in the cargo housing the dome stays on with doors shut.
I remove the bulb in the cargo housing but the dome light stays on.
Crazy! I could unhook the white wires for the ajar switches but I really would like everything to work correctly...
Thanxs and sorry for the long book.lol
