Review on RENMAII-LIGHT 1Set 2-Headlight H4 Relay Harness with H4 Wiring Harness – Enhanced Performance and Dual Ground Fix for 95-97 Tacoma, 88-95 Pickup, 4Runner and H6054 7x6 6054 Headlights by Christopher Isaac

Wiring harness barely reaches my other headlight. Grounding a module without screws or finding a mounting location without simply removing the battery and using a hand drill is a challenge. You could have used a heavier ground pin on these modules and it could have been done better. It was cheap and it works, but hardly in a Jeep XJ. You have enough room to connect it to the battery, but if it was a Wrangler's rear battery, rip out the shrink wrap and extra wire to close the gap. It would be better if they included a small screw, 1 foot ground wire, lock washer and nut so you have options with the module where to ground and mount the module under the hood. It does the job, but hardly. For another $2 they would have a solid product with nuts, bolts, ground wire or even self tapping screws to attach the module. It has the power to power the LEDs, but be prepared to buy ground wire and nuts and bolts to do what they don't include. Cheap!
