How to Turn Off Cigarette Lighter in F150? Step-by-Step Guide

Let’s get back to our main topic – how you can turn off a cigarette lighter in F150. It’s quite easy once you get the gist of it.

The first thing you need to be doing is take off the center console of your F150. Where is the center console? It’s basically the compartment where your cigarette lighter is located. Yes, you need to take off the whole thing to do that.

Nevertheless, it’s quite easy as it only requires you to unplug some screws, and the whole thing comes off easily.

Step 2: Detach the center pin

Now that you have taken out the center console, everything should be visible from here, even the cigarette socket. Luckily, you don’t need to bother about the other things in the center console and only need to work with the cigarette socket.

Simply use a socket removal tool that comes with the kit to take off the cigarette lighter from the outside. You will come across wires that are connected from behind. As you can see what’s behind, simply detach the thick 12V wire that attaches to the “cigarette” socket’s center pin.

Step 3: Connection

Here you will need a 25A relay to proceed with the connection in the cigarette socket. Remember the wire that you have just taken out? Install it with the 25A relay. On the other hand, there will also be a wire that comes with the relay; you have to attach it to the center pin.

Simply put, the wire that was in the center pin first goes into the 25A relay, and a new wire from the relay is attached to the center pin. Overall, the socket, your 12V source, and the relay are now connected in series.

Step 4: Ground wire

It’s important that you provide a second route for the electrical circuit to enter the earth. So that, in the event of a short circuit, anyone working with electricity nearby isn’t put at risk. Thus, comes installing the ground wire with your 25A relay.

You will need to connect any local ground to one of the relay’s two coil connections for grounding. Here, the metal dash structure may be one of the ways to go. There are multiple grounding locations, but the metal dash structure is certainly a good choice.

Step 5: Connecting it to the power source

Lastly, the connection to a power source comes in. As you have grounded one coil, the other one is left to be connected to the power source. Well, you can connect it with any power source as long as it’s 12V and uses a switch mechanism.

Step 6: Getting everything back in place

There you go; now you have the safest cigarette lighter in F150. Now all you have to do is reinstall everything back in place. Starting from the cigarette lighter socket to the center console. Once you have screwed back the bolts, you should have a well-working lighter.
