Not sure about 86 specific's but normally a hot from the battery - often ran from the starter solenoid, a voltage sense and main wire from the alt go there. Sometimes a wire runs from there to the heater blower relay. Also a wire from the fuse block for always hot stuff.

Since you are starting over in that area, suggest a 90's era junction block as a replacement. I got one like this for $5~10 at the local pull-a-part a couple years back. Grab the wires as well as they have factory installed fusible links. It makes it easier to connect new accessories that need battery power.

Thanks for the post, unfortunately I’m not in US to replace it. I must know what massing to order it from eBay, SummitRacing, Amazon, LMC, rockauto, or other Sellers
