Hi, I ripped my block heater cord off the plug. I had to go and buy the $60 cord at Piston ring, as the 2016 Trax, has something thermostatic in the cord. It was suggested to splice the cord, which I was going to go at first, but I will have a code on the car apparently forever. I am trying to figure out where the cord plugs into ? I can’t find the block heater ? Do I get on the ground and look under the engine ? Is it easy to see ? Can I do it myself ? It’s just a plug, but is it covered by a bunch of things ?
