1979 tail lights

[90Bonneville]

alright...i have no idea what is wrong with these lights...kinda have a mind of their own...so here goes...

the passenger side brake and driving light are backwards (as in they are switched like the brake light is on when the running light should be on)

when i turn the headlights on-both of the blinkers are on and stay on

when i hold the brakes and turn on the driver blinker the tail lights wig wag kinda like a cop car

and thats all that i can think of off the top of my head...any ideas on what i could do to fix it without rewiring it all
