I received a set of second hand feed headlights and it's missing the wiring diagram for how to connect them to the existing factory harness.
From the feed turn signal I have 3 black wires and then from the existing factory harness I have a red, black, and green.
I assumed that all the black wires from the feed turn signals were power and just wired them as so, but I was wrong.
Additionally I tested my fog light wiring the day prior and it was working, however after plugging in the turn signals they(fog light) are no longer working, unplugging the turn signals did not turn them back on.
Swapped relays with the horn and the horn is working, then I tried testing voltage at the wire and got nothing.
I read that if the fuse is blown for the headlights it would not make the fogs work, but the headlights are working.
I additionally purchased this feed conversion kit, but I'm unsure if it's for these or the 99spec headlights.
Any suggestions for both of the issues?
Trying to wrap up my build as it's summer just banging my head against a wall...

youre complicating it. you have 1 parking light, 1 turn signal and 1 fog light. each bulb has a power and a ground. the parking light and turn signal wire in like stock to retain the same function as stock. the fog light you have the option to wire how you want. you can do it with the headlights, the stock switch, an independent switch, the parking lights, seat belt, brake lights, radio, boost, wheel speed..... literally whatever you want.

I'm a bit confused, `each bulb has a power and a ground`. I only have three wires coming from the feed lights. Originally they had this white plug but I decided to use a deutsch connector since I didn't have any female connectors for that type of plug.
you can consolidate power and grounds depending on how you want the device to function. the plug itself of no relevance in decision making UNLESS the way it is prewired is how you want them to work. look at the component and trace the wires to make your decisions. 3 powers and 3 grounds... you do with them as you see fit

Thanks for the advice, I figured out the turn signal wiring and have those working.
However I can't get the parking lights to turn on, I tried turning the lights to the first turn and they are not turning on.
Additionally my car has a switch in the center console for the fogs and I haven't had any luck turning them on.
No fuse/relay seems to be blown.
The oe fog light connector will be front center in the hood latch area. You will probe it and check for power when you toggle the switch.
verify the bulbs themselves aren't blown for the parking lights. There are not very many plugs in that area so probe around and look for what gives power when the switch is turned from off to on and wire to that
