## Questions & Answers

**Q: do i really need to heat shrink if the wires will be inside my vehicle? it would not be exposed outside so corrosion should not be a problem**
A: You can do whatever you feel works for you really. I have. And have learned a few times starting with electrical tape (failed with the slightest pull and disconnected). Then crimp connectors (no good due to either over crimping or under crimping). Then heat shrink tubing with solder rings in the tube (works but when fails. It reduces the wire length cutting off connector if needed. Time and money involved. Best way is cordless solder gun. Solder the wires and slide tubing over and heat shrink. To make it secure and moisture proof. Condensation has a way of forming in the oddest places.

**Q: I don't have a heat gun. Do these need a heat gun to be effective?**
A: They work just fine if not shrunk down to the wire.  You can can use a flame but is a little difficult.  Just get a cheap heat gun, , much easier and better.

**Q: will a hair dryer work as a heat source for shrinking the plastic sleeve?**
A: I have not tried a hair dryer. Keep in mind that it requires a hot air to melt and shrink the connectors. I don’t think a hairdryer will not be hot enough to seal the connectors.

**Q: Would these work with electric sidewalk lighting?**
A: I would say yes.  I used them on a boat motor.

Does everything i need it to do, matches other way more expensive brands, the only thing that differs is the crushable steel sleeve, it is a bit thinner than other brands..
