Review on Support Heavy Split Charge Relay by Steve Snyder

Good product, works as advertised. I use it to power my 4Runner's OBA (Onboard Air Compressor). This is for an Air Zenith OB2 Air Computer and the 80 amp relay that came with it was a joke. If you have a high current load, stay away from jacks. Spade terminals will loosen over time, especially when located in the engine compartment where temperatures can vary wildly. When the connector starts to connect poorly, the current increases and with it the temperature of the connection. This leads to the so-called "hot spot". Use ring terminals to securely connect high current load wiring.
