I'm not the greatest guy at wiring and I can eventually figure things out, but I'm having an issue with my headlights that has me at my wits end. My 69 Firebird had halogen headlights on it when I got it. Things were really messed up with wires crossed and one signal coming on when you turn the other one on and visa versa. I was able to get that straightened out with the wiring diagram but the problem I can't seem to fix is the parking lights. They turn off when I turn on the headlights, and the signals don't work when the headlights are on. The rear signals work fine. I've traced every wire and I can't find anything that might be crossed. Has anyone put it halogens and had this same problem?
