Coming from Super Duties I'm surprised Ford still hasn't add upfitter switches option for the F150 like they have been doing for the Super Duty lines since 2005+. I recently got some Diode Dynamic flush mounted reverse lights with a 3-way switch. I'll probably cut off the one they included and use a Carling switch. I'm also planning to add switches for a few other things in the future. Looking for others that added a few switches so lets see your switch panels.

 

I've got a KustomFX four-switch panel, no pics of mine handy but the thread is at https://www.f150forum.com/f122/kusto...panels-520572/

You can add upfitter switches to the F-150, but the I believe the parts are relatively pricey.

I have the same reverse light kit, and used a Carling L-series 3-way switch. It's cut into the dash below the trailer brake controller. I also have a KustomFX switch panel to put in, in the future.

 

I looked at retro fitting the upfitter switches but cost is a factor plus I don't think the Ford Upfitters support 3 way switching. Maybe they do in the newest version but I know they didn't in the Super Duties I owned.

The KustomFX is nice but it doesn't support the Carling switch I rather use.

 

You might want to check with the seller on the KustomFX panel. He may be able to set it up for your preferred switch (unless there's a clearance issue with the switch body behind the panel).

 

I think I read that the Carling switches won't fit.
