So I finally scored another set of JDM one pieces after waiting quite awhile only to find out that Password JDM no longer has their adapter harness’ to go from 9004 to H4H. I can solder so I figured I’d just find a set of the 9004 sockets and make my own harness so I can easily swap back to the 3 pieces should the need arise. The big issue I have now is all the reviews on Amazon for the connectors say they’re garbage and not worth the time or money. What is everyone else running to get power to the bulbs? Links to a good jumper harness would also be appreciated if anyone is still making them.
You can just soder in h4 female connector which can be purchased for cheap local auto parts store or eBay.
I have the connectors that go to the H4H bulbs, just not the connector that goes in place of the 9004 bulb. I want to be able to swap back to the 3 piece lights should a bulb go out without soldering. I’d rather not have to park the car for 3 weeks while I wait for bulbs to slowly make their way up to Canada.
I would suggest to make both the harnesses a quick disconnect the wires from the car females and the ones going to the bulbs males, if you want to go back that will save you from soldering. It would also look a lot cleaner than splicing, just a suggestion.
I found these:
The H4H has the same plug as an H4.
There is also a sub harness with relays:

I kind of like this idea. It also has the upside of me being able to get the parts to do it quickly. I ordered these with the plan of cutting off the H13 connector and just soldering on the factory H4H connector that came with the light but the ETA on them is mid to end of July.
