I have the projector lights in my f150 and want to go back to a set of blacked out single bulb headlights how do i make the high beam and low beam work again only have high beam when mi swapped them earlier

 

Can you identify the manufacturer of your current headlights? A picture would help. Mine came with plug & play adapters to convert the stock 9007 bulb to a H3 lowbeam & 9005 highbeam setup.

 

 

These look identical to mine. Unplug the light blue connector and you're back to stock 9007 headlight wiring. As for the LEDs & Halos, I only a quick look and can't find a quick & easy way to undo them as they are wired differently than I did mine. Examine the box they're connected to, it might yield some clues

 

Where can i get the reat of the wiring harness i already pulled the other for the halo lights and all i had that worked after that was my highbeam or do i tie the wires back into the original light

 

Who installed/wired these lights? If they were cutting stock wiring, they need to be kicked in the nuts. There is no reason to butcher the truck's base wiring in a manner that makes it difficult/impossible to undo.

Are you getting 12v at the low beam pin on the stock headlight connector with the low beams on? If not, you either have a break in the wiring between the dimmer switch and headlight connector or the switch crapped out like mine did.

Grab your multimeter and start testing for continuity/voltage, working forward from the fuse box as follows:

Inside fuse box to main light switch
main light switch to dimmer/multifunction switch
Dimmer/MF switch to stock 9007 headlight connectors

If they all show under 1 ohm, you have a funky switch. Test them per the FSM. My money is on the dimmer/MF switch giving out, my original one was pretty nasty inside upon replacement. So I dissected it, got pictures (see my album/pics) and put the results in for all to see.
