Default please help me with an OEM LED headlight swap

has anyone on here done the headlight swap? i have the basic headlight set and i was able to purchase a set of the OEM LED headlights. i also purchased the correct parts to create a harness to connect my stock wiring to the different plug of the led headlights. what i need help with is how to build the harness? has anyone here done it and can you upload a photo of your harness? i am not good with electronics on vehicles so i am unable to test it myself, i tried and it didnt work out to well. i would love if someone could show me how to make the harness. they have been sitting in my garage for two years and i would really love to finally get them installed.
thanks for any help that can be offered!!!

I am not aware of OEM LED headlights for the CT200H.

A much easier option (which takes like 15 minutes or less per side) is to buy led light bulbs online at EBay or Amazon and pop them in. Cost is around $69 for the pair. You can do the same for the fogs. Easy!!

already have those bulbs for over 2 years now, thats not what i am asking about. i also already have the oem led headlight assemblies, i just need information about making the wiring harness because they are not plug and play. someone made a thread on here a few years ago but they dont seem to be an active user anymore so i can not contact them.

I think you just need the LED ballasts for the headlights and it should plug right in.

This thread is 2 years old. I did a retrofit for my headlights with RX 350 projectors. Sorry I can't help with the wiring.

Much easier to do a plug and play LED light bulb swap. I did mine. Please see my post with pictures. Worked out very well even after 3+ years of service.

In reference to the post above, I would avoid plug-in LED bulbs. They do not have the proper power, projection, or optics to result in any meaningful result. True LED lighting for automotive headlights requires serious power and thus serious cooling--neither of which those plug in bulbs provide. Basically if it's the size of a stick of gum, it's not going to have the physical properties necessary for effective lighting. The overall physical size of a complete LED system including passive/active cooling necessary is going to be around the size of a small coconut.

Yes they've improved since 3 years ago and some applications take better than others, but they can never be on the level of a real LED headlight system. For high beams or turn signals, knock yourself out. But for headlights, I would avoid those.

As for OP, I've no direct experience with that but if you're good with wiring, it shouldn't be hard to rig something up. Find the pins on your new headlight that need 12V and match those to your current car's functions. Would love to see what you ended up doing =)
