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

5 pin relay nothing to say it does its job and clicks when I signal it. I have used two of these plus a wireless remote relay to install backup and downlights on my trailer. A pair of dpdt toggle switches allowed me to "disable" the reversing lights and manually activate these relays when not connected to the tow vehicle. I can then use the dry contacts on the wireless remote to power these relays and activate the remote key. My only concern is the 16 gauge high voltage wires, but the relay says it's good for 30 amps. I would expect at least 14 gauge for the high voltage input/output lines. I run 12 gauge to my battery fuse box, then 16 gauge through these relays and back to 12 gauge 30 feet behind my trailer. I feed my 18-watt LED backup lights a maximum of 3 amps through each relay, so I'm not too concerned about that.
