When making the connection to the cigarette plug (in my case), is it just red to red and black to black?
a cigarette plug is NOT recommended...
some of the heaters can draw close to 15 amps on start up and that exceeds the 10 amp rating for most sockets. depending on what you are running it in, you might have a fuse block you can wire into with a 15 amp fuse. if worse comes to worse, just get a small 35ah battery and wire directly to that. 35ah should last you all night depending on the fan speed youre running
if you decide to try it, just make sure and check the wire and plug connections for excess heat ever so often...it could get hot enough to melt the plastic plug. did that a while back running a tool
