- the connector I have shown is the original connector inside my LED headlight bucket (EX built 2017)
- so yes, that is factory
- everything PeterB says makes sense (I am familiar with electrics and crimping in general - just don't know much about this particular Honda's scheme)
- finally, since the diagram does not show the light bulb, not on the left nor on the right, I am a bit concerned that the connector in the diagram is actually NOT (?) the connector to which the LED unit connects ???
- why do I need the "H4/9003 switching ground polarity module" ?
- would you know what the abbreviation BAT means ?
Thanks
The "BAT" are 12v powered wires from the battery and through the "D" Headlight fuse and "F" Meter/Illumination fuse.
Also the connector is available and can be individually purchased including the tiny wires and pins from a supplier in England.
I did the basic research and concluded that this method to upgrade the headlight into "H4" is too expensive, IMHO, it is more cost effective just to add a pair of projector/spot lights and leaves every wires/connectors original.
BTW, another Forum member from Europe upgraded his 2017 headlight, I cannot find that tread to attach. Sorry.

Please note: Should you buy the proper male connector (from England) you will likely need to use a relay as the Honda wires are very thin and may not have the capability to carry the higher amps requirements of the H4 bulbs.
