It's in the driver side door of a 1995 F150...It appears stock, but I don't see it on any diagrams.

 

Wiring in the door will be : speakers, courtesy (safety) light, power window, power mirror, power lock. The only other thing you can find is a switch thing going to the key cylinder for the alarm.
It's one of those. Door might have been changed and the truck didn't have the same options ?

 

Hum...I wonder where it attaches...and. would it be OK to just remove it?

 

Where does the other end of the wires go ?

 

To a small harness..located around the cylinder lock.

 

Bet it was part of the power door lock system from an older truck (some one may have changed the door)

 

If it goes to the key cylinder, it's for an alarm/disabler system.
Mine has the alarm disable option from the factory.
If you don't have that, you don't need that wire, I wouldn't think.
