SwitchMe 158Pcs Wire Connectors Spring Insert Easy Twist-On Screw Terminals Nuts Caps Assortment Kit

Simple and basic. As long as you have knowledge of wire thickness, these will do just fine for you. They all hold onto the wires really well. I have about half the orange ones left and not one of them has come loose, and I didn't use electrical tape. Used them in my project car to re-wire under the dash and hook up a radio. Will order these again when I am in need.

This was a great buy. Any 'red/green' handyman should have this kit in his utility drawer.;)
