So come to find out the alternator pigtail connector had corroded leaving the battery warning light on. This needs to be replaced. I took a pictures below of the alternator where the pigtail connector must plug into. I need a part number or a aftermarket universal part any help will be appreciated. Thanks

 

If there is no part number on it try here, all my connectors are Ford.

Awesome thanks from the picture it appears to be a 1 cavity connector correct ?

 

Nope. Its at least a 2 cavity or pole connector. But my guess is it gonna be a 4 cavity plug that uses only 2 of the cavities due to the off set of the 2 male prongs in your pictures. The Jag dealer can help you better, and the connectors I've bought from the dealer have been reasonable.
