Q: What temperature should someone use to melt the solder but not burn the waterproof plastic/shrink wrap?

I USED LOW TEMP SETTING ON MY HEAT GUN.. BUT I WATCHED CLOSELY TO SEE WHEN THE SOLDER MELTED AND PROMPTLY REMOVED HEAT. WORKED WELL.

Q: Is this what I'd use to wire my KC lights to the stock fog lights wiring?

Yes, solder seal wire connectors are an excellent choice.

Q: is it possible to connect 3 wires together with these?

Hello friend, thank you for your question. We are sorry to tell you that 3 wires could not be connected with one of these solder butt connector. It would be better for you to connect 2 wires with one connector. Hope this would help you. If you have any additional questions, please feel free to let us seller know. We would try our best to assist you. Thanks:)

Q: can you use a lighter or torch on these?

lighter most cases. torches usually make too much heat. It will take a little while (and a few damaged connectors) to get a hang of it. too much heat burns the connectors. not enough and the solder does not melt. light and steady heat shrinks connectors and melts the solder. thicker wires are a little trickier as they take more heat to melt solder. this does take a little bit of time than crimping but the results are worth it. I used this for my boat rewire.
