For that you will need to be able to do some serious wiring. You will need to find a relay in the engine compartment fuse/relay box that turns on when you turn on the key, like the electric fuel pump relay, for example. Next you will need to calculate the amperage draw of all of the lights you are going to hook up. If the fuse for the relay you chose is smaller than the amperage you need to serve both the fuel pump and the lights then you will need to make a fuse connection at a spare in the fuse box to connect to the new relay output and input (see below). The fuel pump relay has control and supply wires on it. The supply wires actually supply the power to the fuel pump. The control wires simply turn on the relay when you turn on the key in the ignition. You need to hook up the control wires of the fuel pump relay to the control wires of the new lights relay. As stated earlier, the supply wires are then hooked to the relay and, in turn to the supply fuse. Make certain that you use some heavier wire for the supply circuits. Thinner wires may be substituted for the control wires. Solder at the fuse box side and use spade connectors at the lights side...good luck!

I just instalked a new stereo could this have anything to do with my dash lights and tail lights blowing the fuse wen i turn on the headlights

Yes, you could have hook the light wire to a ground. Light wires are usually a dark brown. Not hard to get them mixed up, with low or no lighting when you installed the radio.

How to change headlight bulb

On the back of the headlight where the wires enter, you should be able to twist and remove the lamp holder. Be careful with the new bulb if it is halogen, do not touch the bulb!!

2007 Ford F150 STX, I need the Wiring Diagram for Lights (Headlights, Running/Parking/Turn-Signal)

Go to either and register your vehicle for free, or for the same wiring diagrams. Powerbox layouts are also provided.

Now I want to add that if the new lights are like the HID factory type, you may need 2 Relays and heavier wiring to the lamps. Now sure if the Alternators are the same either.

I hope my solution helps.

Lt. headlight low beam wont work after replacing the bulb.

I assume it didn't work before you changed the bulb either. You'll have to check for voltage at the bulb socket when the low beam headlights are turned on. If there is none you'll have to trace the wire back to where it splits from the right low beam headlight. If there is voltage there you have a problem with the new bulb.
