Review on 🔌 Complete Universal H4 9003 Relay Harness Conversion Kit with Ceramic Sockets - Compatible with H6054 H5054 H6054LL 6014 6052 6053 by Vivek Allen

This wiring harness was perfect and very easy to install! I bought LED headlights for my 1991 Toyota pickup and they didn't work properly with the stock wiring harness. I plugged them in and moved the pins in different directions and they didn't work properly. The brightness stayed on when the low beams were set and when I clicked the headlights went out completely. But this wiring harness solved the problem and was very easy to install. It took me about 30 minutes to hook everything up properly and clean everything up with zip ties and such. I definitely recommend this trailer!
