Review on 🔌 Partsam H4 Headlight Relay Harness Kit for 7x6 and 5x7 H6054 Headlights with Ceramic Wiring Harness - Compatible with 88-95 Pickup Headlights, 95-97 Tacoma - Fixes Dual Ground Issues by Anthony Hales

First, there are no instructions. When installing, the wire connecting the fuse to the car battery popped out with very little pressure, so I had to buy a separate built-in fuse and solder the wires, doubling the installation time. You also need to buy two nuts and bolts to fix the relay to your car which are not included. I used M6x1.0 screws and they fit perfectly. it does the job, but it's cheaply made, the crimping is poor, and all the wiring is cheap. The wires to the headlights are only 20 gauge, the red wires to the fuse and battery are 16 gauge I believe, but they're so cheap they don't have the usual tag to identify them. I would spend a few bucks more and go for a kit with thicker wiring and better quality.
