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

I wanted to install this harness to replace the headlights on 69 GS with LEDs with H4 connectors. More caliber. So if you're using them to work with higher wattage bulbs you'll probably be disappointed, replacing lower wattage LEDs might work for you. The second thing I noticed is that the connector to the OEM connector matches the H4 connector. , I don't have to rotate all 3 connectors to fit the 5006 Hi/Lo Beam in the 69 GS wires. The above lamps may need modification. Being Toyota upgrades I expected them to be wired incorrectly and I'll end up swapping the wires to match the OEM side of the harness. I would provide an image from the web, but I don't own the rights to the image. I may switch to 12 or 14G wire size for power as this 16G wire size is 20A max for less than 2ft and has a 30A fuse. It's a good concept if it has the power and ground wires upgrade to 14G, that can handle the load, and if they let the wires out of the harness at the OEM end and give instructions on how to place them in an orientation for classic USA and 1 for Japan/Europe etc, then they have something here .
