HID to LED..cant figure this out

I took out the prior owner's HID wiring. That headlight was wired from the battery terminals through a relay, to the HID transformer to the headlight (Mocked up wiring in an attached picture) Low and high worked but overall not good lighting. Bought an Eagle LED halo with H4 connector (I think its called H4, its three pronged)

The connector on the bike wiring harness is rectangular 4 pin. The connector to the light is a rectangular 3 pin on one side to the H4 connector on the other side, where the light directly plugs in.

It looks plug an play but I have no lights. I attached a hand draw diagram and actual pictures on the connectors. What am I doing wrong? Can someone draw a wiring picture? Thanks for the help I searched but could not find anything definitive.

Rusty - yes it did come with instructions but very, very basic. Unplug connector, place new bulb in , reconnect connector - sorta like that. no wiring description at all.

I had a very similar issue but mine previous owner cut the harness altogether.

Just remember this coming from the bike -
White = high beam
Yellow = low beam
Black = ground

Image is for 2010 but should be the same cant imagine HD changing that.

NexVision - Thanks I think this helps. I believe the wiring is good back to the lo/hi switch (I'm terrible at bike/car diagrams). I don't think it's getting positive power because the old HID was wired directly from the battery terminals and I yanked that out, however the low high beam switch functioned well. I'll check the fuse and try tracing wiring. Any other suggestions?

OK here's is what I see so far. Ground (blk) is good. No power coming on White or yellow leads (hi/ low beam). I do not see any fuse position labeled "lights" in the fuse box area. Is there an in-line fuse from the positive battery terminal? All other circuits on the bike appear to be working.

You should have a 15amp circuit in the fuse block going out to your high/lo swich and then from there to the bulb. Look for a 15amp in the fuse labeled lamp or lights. It maybe in the bundle u pulled off trace everything.

No fuse labelled "lights" , "headlight" or anything close. What I pulled off I believe was the prior owner's wiring loom for his HID installation. I don't believe Harley would have a wiring loom bolted directly to the battery terminals from the factory?

The Lights fuse is fuse no 6 in the fuse box under the rear seat. I think you are just looking at the front fuse box!

Hid lights require different wiring requirements then factory, as you found when you removed the HIDs. PO chose to draw power directly from battery. this wiring has nothing to do with your factory wiring harness. pull all the fuses and check them if in doubt. there isn't that many...

Coastrider - yes I was looking under the front cover initially however last night I looked under the seat and did NOT see a fuse box. I will look again tonight and report back. It will be embarrassing if I find it because I work on EVERYTHING on my house, car, and bike myself. I'll be disgusted with myself, then have a beer and get over it. lol.

Hey everybody...Did you know there is a second fuse box under the seat??? Yep, believe it or not, it's there! Boy do I feel silly.

Ok pulled the fuse to the #6 lights circuit- looked good- tested with my volt meter (cont.) and it wasnt. Swapped out for a good fuse, plugged short stock wiring extension in, plugged headlight in and...........IT works!!!!

Hi, low, and halo working fine and mounted back on bike. Thanks for the help (once I found that damn fuse box all was well).

Time for a beer!
