I have recently purchased a factory alarm for my 2003 F150. When I went to have it installed I was told one piece was missing. I have the brain and small box that holds two fuses. Can someone tell me what I am missing and where it was originally placed on the truck so I might be able to get one, pictures would be great.

Someone mentioned a third piece but has never seen it. Does anyone have illustrations?

After seeing other post online however I am now wondering if it’s possible to add the remote start capability with the new dual keypad to my existing alarm which is also for a 2003 F150.

My last question is if I can’t do the last option, can I add the complete new system to my 2003.

Please Obe'won you’re my only hope.
