I want to add running lights to my 08 f250 that currently doesnt have them. Is the wiring under the headliner? or will i have to run all new wiring? I searched but couldnt find anything on this.

 

Welcome to FTE. I don't know for sure about the 08 models, but in the past you've always had to run new wiring for them. It's not too bad a job to do it.

 

There are a few threads about the installation, but I don't know if they mention having to purchase the harness separately. From what I have seen so far you will have to get a new harness. The upside is they are relatively inexpensive. The downside is that they are a pain to install because of tight spaces that you have to work in to route the wire and get it plugged in to the main harness behind the passenger kick panel.

If you're willing to do drill the ceiling yourself, the rest shouldn't be that bad. I've seen some kits on ebay that are "reasonable" that come with lights, harness and template for around $125 - $150. There are also aftermarket kits, but I believe they use the factory harness as well.

I'm hoping to get this mod done myself this summer.

thanks for the replies. i found a few useful threads after i started searching for "clearance" lights instead of roof or running lights.

 

there are two different harness's. one for trucks w/the overhad console and one for trucks without the wire harness.

There is also a different harness for pickups with Satellite radio.
