lighting issues

[cougarman]

For some reason the hazard switch only turns on when the button is depressed and the right blinker is on? I'm assuming someone attached the power wire to the one that gives that turn signal power. What color wire is this on the hazard switch anyone know and what was it supposed to attach to?

Also for some reason my front left and rear right yellow/red side markers do not light up. Along with the passenger side tail light, both backup lights and both license plate lights. I noticed that the backup light bulbs were rusted into there socket. So I removed them with needle nose pliers. But now the bulb holders are full of rust. Is there any easy way to fix these or do i have to replace the whole bulb housing, and where do I find them. When I first got the car neither rear turn signal worked, which I found was due to a bad ground going to the frame. Are there additional grounds for these other lights that go to the frame or no? The car is a 1981 Spider.
