Review on EPAuto 5-Pack Relay Harness: 30/40 AMP, 12V, 5-PIN SPDT Bosch Style - Ultimate Power Control Solution by Andy Baudoin

CONS: All 16 AWG wires that shouldn't exceed 10A continuous. They also claim -40 to 125 degrees ambient temperature. IMPOSSIBLE The cable is rated for 105°C. I would only use it for 10 amps or less and up to 90C ambient to account for coil temp rise and current through contacts and 16 gauge wire. I tested this relay and at 25A for 15 minutes the relay and wires were over 75C in an ambient temperature of 22C in my basement. Pros: for something for $2 + for the relay, connector with wires. Very good, but don't trust the 30-40 amp temperature and current readings. Just be careful with your app and don't believe everything you read.
