Thought I’d share, recently installed this Rugged Ridge bumper and winch and found there was plenty of room for a NOCO block heater receptacle. Like a small extension cord it has a male end under the tethered cap and a female end on the roughly 18”cord out the back. Pretty slick, and apparently there is one with a longer cord but I found I could get the OEM block heater cord to the bumper taking the grill off and fishing it down. The cord that comes out the back is out the side of its housing keeping rear protrusion to an inch or so. A little dielectric grease and some self vulcanizing rubber tape to seal the cord plugged in to one another and all set.
