Wiring issue 92 toyota

aight so ive changed the flasher underneathe the dash as well as the tail light relay on the fuse panel underneath the dash. I changed the wiring harness in the tail lights. I still have the LS directional on when i turn the parking/headlights on. Also when i turn the parking lights on i have nothing in the rear (but every thing else works. blinkers brake lights) The parking light on the LS very very dim, right side is normal. Ive changed all the bulbs in the truck as well. Any idea what it could be? ANy thing is better than what im thinking right about now.

sounds like you covered everything and its still not working. just make sure your not missing a ground somewhere or have a bad ground connection. only thing i can think of especially when you say one side is dimmer than the other.

there is a jumper wire on the tail light housing itself. It is a ground if it is loose at the plug this will happen. Are you running stock or aftermarket tail lights. Most aftermarket euro lights dont have this jumper on them you have to do it yourself. Check that and it should fix your problem. It is definately a ground issue.

and make sure that u dont put ur bulb in backwards or it wont work rite....
