Unknown plug and dim battery light

[jordanhdi]

I was routing around my engine bay today and I found this plug and I can seem to find anything that it connects too.. Also a dim battery light. I've checked the alternator output it's about 14v so it can't be that.. They are bother me. Anyone know much about this

That's an unused plug for the air dozer, I assume the car us before mid 2000

dim battery light could be a bad earth somewhere.

Yeah the car is mid '99 and where is the most likely bad earth strap
