Reverse lights !

Yes , I have a 2004 Ford f 350 crew cab dually 4x4 . It has the 6.0 desiel . And the tow package it has the little button on the colum shifter . And it's an automatic . My problem is my reverse lights stay on !!! The truck is in park and the truck is turned off and the key is out of the ignition . And the reverse lights stay on ??? The truck won't start . So I have disconnected the battery cables . What could it be . I think it has the 5R110 transmission ??? I'm not sure about that ??? Where is the neutral safety switch located ??? Please if anyone can help ??? Let me know ??? You can email me at jakehd2008@yahoo.com . I hope someone can help me soon !!!

Unplug the reverse light bulbs for now.

When you do, look at the wiring, as it might be in bad condition and somehow shorting how.

Everything I've looked up says it's either on the left side of the trans or it's under the dash to the right side of the column.

What does won’t start mean? You turn the key, engine cranks and cranks and cranks but won’t fire up?
Or you turn the key and nothing happens? Do any electrical components work? Radio, headlights?

Jake,

I may have encountered a strange coincidence related to your problem, or maybe unrelated.

Just today I took my '06 SD-250 SC fx4 full bed for a tour. I came back, backed her into the stable and went about my bizz. I then went out for unrelated stuff and I noticed her brake light on. I pulled fuses, battery, switch at foot pedal - no love.

Then the "duh" alarm went on! I saw the light on for the factory installed dash mount "Draw-Tight" trailer brake system box. I slid slider back "home" and, yup, the lights went O-F-F! Check it out. Maybe you've got something with crossed brake to rev???

Good luck, Noel.

Pull fuse F8 under the dash and see if the backup lights go off.
