Looking for install ideas with photos to add an AC Port plug to my truck. I don't run my truck enough to keep my battery in topped up. Planning on permanently installing a NOCO GENIUS 2D battery maintainer. I found several examples on Dodge, Ford and older Silverados but not much for the 2014-2018 models.

My truck came with a block heater. It was -20 last night here in Ottawa and no more than -15 today so I thought I would plug in the block heater and see how it worked. I plugged in the heater cord that came with the truck and checked the voltage =120 v. Was curious about how much draw there is but my amp probe showed zero amps when plugged in. I checked the continuity of the cord, all good. I checked the resistance of the heater at the plug on the truck , it shows open circuit. I read on other posts about block heaters that the thermostat is in the cord itself. It appears that GM has moved the thermostat into the heater itself on the new models so that the cord cannot be tampered with. For me I would just like the heater to work when I want it to, not when GM feels its necessary, I think -15 is cold enough to warrant use of the heater. Attached are pics of the cord that came with the truck -2020 Sierra SLT
