Lights issue

Ok so i just replaced both front fenders on my 97 TJ. I replaced them due to rust holes i figured it would be easier to change them out than do all the bodywork (not from front end collision damage). I reused all of the driving and parking/turn lights. As far as i can remember before all the work everything worked. this is what i now have:

neither light on either of the fender flares works.
the passenger turn light works correctly.
the drivers turn light does not illuminate when the lights are on and when it blinks, blinks very fast (like when a bulb is out). If i play with the wires i can get it to blink, but its fast and not light with the headlights. and when the healights are on, the left turn signal light on the dash is lit.

All of the associated bulbs are good and all of the connectors are back in place. Ill see if i can order a whole new harness and socket assembly for the drivers fender light. but why would the running lights on the fneder flares be out? did i hack up a ground wire somewhere?

Sounds like broken and brittle wires inside the looms. You'll need to pull the wiring out of the wiring looms and inspect them closely for breaks/pinched areas. While you're in there, check the ground to each light. You can always attach a piece of wire to the outside of the bulb sockets to a good ground point to verify the grounds are good.

The lights on the front fender flares are only single filament bulbs, and they don't have an independent ground. They use what is commonly referred to as a floating ground. When the lights are on, the side marker is grounded through the front turn signal filament, when the blinkers are on, it's grounded through the front parking light filament. That means that if anything is wrong with the front fender light (like a bad ground or bad connection, or bad bulb it will effect the operation of the lights on the flares.
