While fixing my headlights according to https://blazerforum.com/forum/audio-...ase-help-4999/
i discovered this plug on the right side of the rad. Anyone have any idea what is for??

 

Where does it lead to, trace it and see what wiring it connects into.

 

looks like a 4wd indicator plug. could be wrong tho. definitely trace and look it up on a wiring schematic

 

could that be the plug for the fog lights mine does not have them but i have the harness behind the switch to hook them up inside but no idea where they could hook up outside other than right there as it looks to be right about where'd they sit
