the heat wont turn off when i turn off the truck

A lot of things labeled for one thing are used for something else, but trust me, the two different sizes work perfect for the red, blue and yellow connectors. And the little spike makes sure it's crimped secure as shit and not just squeezed with the portion that says insulated on your pair. I've seen some come undone, now granted it's operator error from either not enough pressure or wrong wire gauge/connector used, but using the ones I mentioned RARELY come undone because of the piercing like action from that little spike.

Those are for non insulated connectors only. I use the 1005 instead.

Itll keep. That solders melting point is not going to be reached by the current flow passing through that connection because the connection is not loose which would cause a resistance and ultimately end in heating up to the point the wire insulation starts to melt and possibly even catch fire.
