I recently ordered and installed the Amp Research Powerstep. It came with wire connectors called Posi Taps. They are awesome! So easy to use! I was skeptical at first because if it's not a pain in the ass to use, it probably doesn't work very well.
I was so excited when I used these I almost wet myself.
Maybe I'm late to the party and everyone knows about these, but I thought I would share the product with you guys. Here is a link and the picture. They have a few different kinds for different applications and different wire sizes. Happy Modding!
