Posi-Tap Red (10) Inline Wire Connectors 18-24, GA, AWG, Electrical Fastener, WIRE NOT INCLUDED

These things are a Godsend for quick and easy connections working inside the car if you don’t solder or you have no confidence in yourself to do it well. I used them to connect a reverse camera that comes with fragile, hard to manipulate, ultra thin wires that wouldn’t crimp well. I was able to slice the sheathing back on the camera wires and get a tight, solid, tug-resistant connection to the power and ground wires out of the head unit. It's really as simple as advertised. Put the main wire you want to splice into into the cradle on the one end, screw that tight until it the spike goes in and you can't turn it any further. Put the exposed twisted strands of the wire you need to tie into the existing line into the cap on the other end and screw that until you can't turn it anymore. Protecting it all with electrical tape doesn't hurt as a little extra insurance. I ordered the connectors for 18 gauge wire but used them for 16. This guarenteed a snug fit in the cradle for the main wire and the spike going in solidly in through the middle. Got a tight, solid, dependable connection with about 10 total minutes of work. Camera works great. Didn’t have to mess with splicing or cutting the head unit wires and risk damaging them, or a wrap and tape hack job that might give me problems later like the last one did. On both ends of the connection just don’t be afraid to twist the screw until you feel like it won’t turn further.

These allow you to tap into existing wiring easily, so you can connect, for instance, your backup camera's power supply to the b/u lights and, up front, to 12V accessory (think lighter socket). Really simplify the splicing process. Don't hesitate to use these. You will thank yourself.

I've used Posi-Tap connectors to install reverse cameras on two different cars. Reverse cameras often need to tap into the car's backup lights to trigger the camera on when reversing. Posi-Tap's allow a quick and clean way of making a wiring T tap without stripping any insulation from the OEM wiring harness. I'll always have a few Posi-Tap's in my wiring kit.

Can be helpful for tapping into a wiring harness with minimal interference.

I've used these in the past for car reverse camera, fog light, etc.... Makes it quick, easy, and clean.

Not cheap, but nice things usually aren't.

Not sure what kind of review you'd expect. The positaps work as advertised.

I'm not an electrician. I don't even particularly like working with wires and electricity. But I've used posi-tap connectors on multiple motorcycles and in my SUV with no issues. The only time one didn't work on the first try, I simply moved the tap's location (they're just as easy to take off as install), and it has worked ever since. Won't ever splice wires without one.
