Review on Connector Harness Battery Connect Disconnect Exterior Accessories by James Maruffo

Excellent design. Can assemble and disassemble the connector as needed. Fits very tight. It's hard to break up. But it creates a great connection. A bit of dielectric grease to reduce corrosion and now it still holds up nicely but is easy to disassemble if needed. A bit bulky but perfect for 6-8 gauge wire. I would use a smaller spark plug for a 10 gauge or smaller. This will work, but a smaller connector is better for this application.
