The headlights installed pretty easily. Open the hood and remove that big rubber flap. It's held in by one plastic screw and plastic retainer. Be careful not to destroy this since it's flimsy.
The three 10mm bolts came out quick and one good tug of the headlight housing and the headlights were out.
The time consuming part was wiring the halos and LED running lights. I chose a lead coming off the blinker light. In retrospect, I should have taken the power off the side lights. I wouldn't have to figure out which lead was for the running lights and which lead was for the blinker. Oh well. Got everything wired together and put quick connectors on the leads for the halos/running lights. That will allow the future removal of the headlights to be quick and easy.
The HID was a bit more work. Initially the HID would come on for a quick second then go back off. I even tried installing a capacitor to fool the on-board CPU, but that didn't work. I was suggested I try a relay. I'll give that a try tomorrow. I just put the halogen bulbs back in that the projector headlights came with.
Put the projector headlights in alignment with the fender and pressed it back into place. The three 10mm bolts back in and replaced the big black rubber flap.....that was all there was to it. Pretty simple. These headlights are a hundred times easier than the older F150/Expedition headlights prior to 2004.
