Ok I put long tube headers on the truck and I have the back 2 on but my front 2 need to be plugged in but they arent long enough I need 2 feet of more wire to plug it in so I was wondering if there is any that are extended I could buy or I have to splice wires and extend it myself

 

I just did the same thing a few weekends ago. You can buy 18" extensions online for like $30. You won't find any labeled for an F-150, but I've been told that the plugs are the same as a Mustang, just make sure you get the right ones (I found two different styles).

I was being cheap and didn't want to wait, so I just cut and spliced wires to make mine longer. I haven't had any issues so far and only took me a few minutes. You might want to find some high temp shrink tube to put over the wires since they might be pretty close to the headers in places.

The nice place about doing it yourself is that you can make the wires as long as you want, so you can make them long enough to route the wires far away from the headers.
