I have been cleaning and fixing things on a 1996 80s series landcruiser and was hoping for assistance on identifying a strange wire. There is a red wire that was hooked up to the positive terminal of the battery. I traced it to being spliced into a black wire with a white stripe over near the washer fluid reservoir. I was led to believe generally a black wire with a white line was a grounding wire but that may not be the case. I'm still learning a lot about this car, but was wondering if anyone could let me know if that this wire might possibly be for. I have included pictures. Please let me know if you need any further info and I will be happy to provide it.
