If its the one with the rings the only difference is that those need to use a crimp ring to connect. the one I am selling allows you to plug it directly into the cap.
Also as the cap has 4 connections in the + side (2 4gaguge and 2 8 gauge) you can use it instead of a distribution block if you have 2 amps.
It must been great living in the 70's, when cars were much interesting and lacked safety features. Jeremy Clarkson of Top Gear gets in the wheel of a Reliant Robin and went rolling around on the streets of Barnsley...
