hey guys, got a quick question, ive got a 06 f-250 diesel, the temp is dropping below 10 degrees tonight, and im at work, i was able to walk outside and take a quick look behind the bumper and couldnt find a plug. was just wondering if there was a way to check by vin# if my truck is equiped with the plug, or if i have the engine block heater and have to add the plug. please dont think im lazy, i work at the 911 dispatch center and dont have the time to spend outside tonight laying on the ice under my truck!!! thanks in advance
