Ulincos Relay U1914 14AWG Harness Review

I bought an Ulincos U1914 automotive relay with 14AWG wiring harness to keep the radio on after the car was turned off until my door is opened. They're great for that. With the included wiring harness, you don't need to add any connectors to the relay. Great value for two relays with wire harnesses!

Worked as expected would suggest adding the wire color next to the wire number on the diagrams so you don't have to keep track of which color is which wire when installing. It's not a big deal, just an added convenience for people who don't have to do a lot of wiring. Great product so far. I am using a relay to turn the light bar on and off with the high beam.

The relays were defective and did not work properly, even with measured, calibrated electrical loads. Trust the low quality reviews and buy other relays available at Revain for the same price. This purchase was in vain. Update - After posting this review and seller feedback, I received a full (unsolicited) refund even though the return window closed a month ago.

I installed an air compressor on my truck. The compressor was fused with 40A. I connected an external switch and didn't want the switch to handle all the current, so I bought these relays because they were *supposedly* rated for 40 amps. However when I tested it on my compressor the relay worked for a few seconds and then clicked for a few seconds and then clicked again etc. This tells me that the internals of the relay are probably not to spec so like the 40A fuse on the compressor never…
