Dome light not working

Wondering if anyone has a wiring diagram for my 1999 F350 crew cab for the dome light circuit. It wont come on with the light or door switches. I can make them come on by grounding the #1 relay in the fuse box. Checked the light switch and it seemed to be working properly, sending a ground signal out when moved to the 'dome on' position. I have searched threads for 2 nights and cant find anything. Thanks

Thanks for the help, it looks like I have a faulty GEM. I'll make sure i'm getting signal into it and let you know what turns up.

Good luck. Btw that was found with a Google search for "99 super duty dome light wiring diagram" for future reference and those playing at home.

Had the same problem with my 2001 250 SD, did the research, was going to replace my GEM also but decided to replace the top white relay for $6.00...Bingo!! Works every time, all the time..
