I am looking for a wiring diagram for that taillights for a 1999 f350 pickup. I am working on a friends truck that doesnt have any taillights and I would like to have a diagram in hand before I get started on it.
thanks

Which "taillights" are you working on? The stop/turn/parking lamp circuits are spread across two sections in the factory schematics. Also, identify the body style of the truck, there are some variations between the versions.

 

first .. make sure all fuses are good.. I know.. but check with test light..

 

Not sure the exact model. Just that it is a 1999 f350 crew cab 7.3 I guess I assumed it was a hd or super duty.
I tried to find which fuse it was in the the fuse listing in the manual but none said just tail lights. I checked the bulbs which were good. I did notice the front running lights did work. I would assume they would be on the same circuit. This truck if pretty rusty and I am thinking it will be a connection problem at one of the plugs in the back of the truck. I am going to get the truck tomorrow to look at it.
thanks
Jeff

Thanks for posting up the link. I will post what I find wrong.

found where the wiring harness that runs to the back of the truck had been pulled loose from a hanger bracket and had rubbed into the frame rail and had broken the tail light wire. Only way I found it was the plastic ribbed harness conduit was cut away where it had rubbed.

Good to hear that you found it.

 

Hey brd 7666
I have a early 99 with some trailer lighting issues. The link to the wiring diagrams don't work anymore. Do you have any access to them. Basically, no power to either side of the fuses 1,3,5,7,9. That entire row seems dead.
The really crappy part is....it's been stolen twice, recovered twice, and you don't really know if the dealer got it fixed correctly after recovery.
