Does that wire go into a ford factory connector in the kick panel? If so, what color and how many pins is the connector? What's the wire color it's tapped into? What are the other wire colors in the same connector?
To ID it, i'll need to identify the connector it goes into first, and from there i can tell you what that wire does
Car had a Alpine car alarm when i bought it. Took the brain box out a long time ago and would like to remove any thing from it when i find it but dont want to mess up something up.
