Up-fitter switches?

My new truck came with four "up-fitter" switches. What have any of you used yours' for? How difficult was it to wire?

On a 2009 that I had I found the wires for the upfitters under the dash on the left side, Found wiring in the owners manual. These only work when the ingition is on and have amp rarges from 5 to 20 amps depending on which switch is used. I was using the 20 amp for a small inverter for my laptop, The 5 amp for the Wilson repeator and one of the others for my CB radio.

I have them too but have no idea what to use them for. I guess I may put some blue LED lights on and use one of them for the lights. The wires for them are found on the steering column and all you have to do is hook into them. Not hard at all.

I've used 2 so far. One I use for bed lights that I installed. The second I use for the Tire Pressure Monitoring system (don't use it when the trailer is disconnected). For us older, not a flexible as we use to be, types the wires were a PITA to connect to.

One of them is used by Ford to set as a High Idle switch, if you would want it. Will set the idle in park w/brake on at 12-1300rpm if you want to run AC or other power users for extended time.

Aux switch

Ditto on Wingnut: One should not let the 6.4 idle too much. Winter use and I get out of the truck, I bump mine up via the uplifter. Summer, I want the A/C working full blast. I Like the idea for inverter. We have only been using the lighter port, with no probs. THX. Merry Christmas.

I have to agree with K-Star, unless you are a double jointed 9 year old, you will have a heck of a time laying on your back trying to find and connect to the switches . I have a CB radio and TPS on one, a video monitor for the trailer cameras on a second and the third for the air pump for a Kelderman air ride rear suspension.
I must say though that using the upfitter switches makes a much cleaner install for these 3rd party accessories.
It makes the job a bit easier if you take off the side and steering column dashboard panels.

1 Fog lights.
2 Air horn.

I paid someone to connect them rather than pay my chiropractor after a DIY install.

1. CB Radio
2. CB Linear... so you can hear me talking with a toaster
3. Antenna cut-out so the XM radio works better
4. Empty, but considering an inverter

Oh, and I'm with Bruce and Jenna, installer over chiropracter everytime...
