2001 toyota seqouia Dome light

Hi to all,

I installed a 10.4 TV screen on my 2001 toyota seqouia it worked prefect, after two days later the DOME LIGHT won't turn it on and off  when I open or close the door, I have to mamully turn it on and off, I check the fulse which is OK.  please help. Thank You.

where did you grab this wire?  is the screen needing a negative or positive trigger?  What kind of screen?

Well, your truck puts out a negative trigger, It's a white wire at the BCM under the drivers dash, its pin number B8.

If your going to a fuse you are more than likely using a positive trigger, 90% of screen domelights use a negative trigger, this may be your issue. Has it ever worked? Are there any relays involved?

Thanks, Defective

My screen is  ---> http://www.audioinmotion.com/generic49.html scroll down to the last two where it said Emerson 10.4" Flip-Down Monitor (MT-2500) 2001 Toyota Sequoia with Sunroof, that is my truck.
