Review on 🔌 H4 LED Headlight Wiring Harness Kit - Negative Switched Conversion - Fused - for 9003 H6054 H5054 H6054LL 6014 6052 6053 - Suitable for Subaru Toyota Head Lights by Dustin Woodrow

This is rubbish. Plugged it in to test before a full install and it didn't work properly. The high beams stayed on and the relays were questionable. Just the slightest movement of the relay turned on the high frequencies, which is definitely not desirable when installed in the front of the car. Cables were cheap too. I'm pretty sure it said they were 12 gauge, maybe there was an insulator, but the wire itself was 18 gauge at best. Also, I was better able to crimp the terminals with my bare fingers. Even if it worked properly, I'd have to check each connection to make sure it wasn't broken. At least 3 wires popped out of the connectors with ease. Connecting the headlight to the wire harness, push out 2 connectors. It wasn't expensive but rather annoying that it didn't do what it was supposed to. 91 Toyota MR2 in case anyone is interested.
