I've used several of these that I got at a local auto parts supplier. Very heavy duty with locating pin.

This is the brand name that was on the box.

Couple these with Group 31 Batteries and some good solid 2/0 welding cable used for battery cables and eliminate a lot of high dollar problematic issues with OEM gear.  Can also make your own custom cables for a fraction of what OEM charge  with good copper crimped on conductors and heat shrank connections.
