Hey guys, just was wondering if anyone attempted to upgrade to JDM late model, Impreza LED headlights I bought fox beam conversion harnesses, and everything works except the high beam. I can hear the relay clicking when I push the stock forwards and I get the blue indication light on the gauge cluster but the beam pattern doesn’t seem to change. directionals work low beams work. DRLs work fog lights work (shut of when high beam is turned on)

If you are upgrading to JDM headlamps, please please please adjust the aim on your driver side to be lower. They're going to be aimed from the factory as our USDM passenger side (higher towards the presumed outside of the road) and this blind driver's in your oncoming traffic (JDM outside of road).

Additionally, check your fuses, LEDs when plugged in backwards may engage the relay, but blow your fuse.

Yes the headlights are getting adjusted asap the car is in storage for now until the salt is off the roads, i messaged Foxbeam lighting, i still cant tell whats going on, if the high beams are coming on with the low beams or not working, if i pull the stock towards me with low beams off, drls on i get light and the blue high beam indicator on cluster, yet if the low beams are on and i push the stock forwards, light out put doesn't change just the fog lights shut off, im going to check fuses but i have my doubts as i think the way the high beams work on these lights there is a cut off that just lifts

Headlight Wiring Diagrams

Regarding the potential for a fully-functioning LED headlight retrofit into Premium and Sport models, does anyone have access to wiring diagrams for halogen and LED headlights in the 2017-18 Impreza or 2018 Crosstrek? I have a 2018 Crosstrek with LEDs as a loaner for a few days (LOVE the SRH...

I'm not sure how different the pinning is on the facelift LED's, but this could be a good resource to try troubleshooting.

Update found the problem JDM headlights are pinned differently than US DM and the only one I’m really missing is that blue high beam positive leads to nothing on the JDM headlight I just need to know which pin on the JDM headlight is the high beam positive

I think AyyeLmao is correct about the wiring being different in the facelifted LEDs.

Mine was the 2017-2019 ones.

They’re different I have a 2023 Impreza that I’m trying to install facelift LEDs on in the high beams are actually missing both pins on the JDM headlight socket. I have a Fox beam lighting adapting harness that is meant for the US DM socket. it is not the same, I have that wiring diagram but unfortunately it doesn’t help me if people keep sending it to me. I understand they are trying to help but I need one for a JDM headlight.

Mine is a JDM set as well.

I didn't not use an adapter, which allows me to pick where to pin the wires on the 8 pin plug.

Did you take a look at the wiring thread I linked?

The adapter is not the issue, its the jdm head light socket is, some photos to explain

Let me clarify.

I did not use that JDM headlight socket to install on my vehicle.

I took that 16 pin plug thats attached to the LED housing, unpinned the wires from there, took those wires and pinned them to the 8 pin plug that was behind the halogen housings.

Then i just plug the 8 pin plug back into the car and everything is working.

The 16 pin plug is just left to the side, not plugged into anything (the other wires that we dont need are still connected to it).

 

[tiramisu403]

Looking at your pictures, if you really need to use the adapter, I think you can just unpin the high beam negative and positive, and pin it to the correct location as well.

 

[thelegacygtguy]

You more than likely have the answer I need and I’m not trying to piss you off trust me, Ok so did you trace the wires then what I’m trying to figure out is if you took the pins out of the JDM headlight socket how did you know where any of the wires connect to if we only have a USDM wiring diagram for the usdm 16 pin socket

 

[thelegacygtguy]

I don't know what the correct location is thats what i need to know I guess I gotta take the headlights back off the car and trace the wire to the high beam

So the adapter you are using, does it connect the 16 plug from the LED housing, into a pigtail where 1 side is 16 plug female, to an 8 plug male?
(Sorry! I didn't use an adapter so I'm not sure which kind of adapter your using)

 

[tiramisu403]

I'll try to explain it as simple as possible.

You just need the positive and negative for the high beams to go to the correct location on the 8 pin (car side).

If you can find a diagram for your original headlight 8 pin plug, you can find where the 2 wires are suppose to go.

You would look on the 8 pin side of the adapter to see which 2 wires are in those 2 slots, and follow it to the 16 pin side.

Here you can either unpin the 2 wires on the adapter side and pin it to match where your high beam wires are on the headlight 16 plug, OR unpin the high beam wires from the headlight 16 plug, and pin them to the slots where you traced the 2 wires on the adapter.

If your wiring is the same as pre face lift (I think its the same, half the cars there are post face lift models), it would be 6 (positive) and 7 (negative) on this diagram.

That side is correct im getting voltage for the high beam on both the 16 pin and 8 pin harness, but dont know were connect it to on the jdm head light because the pins are not the same as usdm, so i dont know where the voltage should be connected too on the head light its self

It sounds like you just need to find out what pin on the headlight socket is the highbeam positive and ground. But looking at the diagram it also looks as though the "DRL bright +" is blank on the JDM headlight plug as well. Is that function working for you?

When I was soldering mine, I found it invaluable to wrap tape around the wires and label them. I'd recommend doing the same as you're going to be trouble shooting what connections are what. It's going to be a little trial and error, but you have most of the functionality, so you've got a good baseline. Are you more comfortable re-pinning the harness or the JDM plug?

[/QUOTe probably the harness side since I’ll have a schematic of how to put it back. If I ever went back to USD I’m headlights.

Okay that'll work out nicely for labeling as well, since you already know what each pin is. I'd label each wire, and just unpin that whole plug on the harness. You can eliminate many of the the pins on the JDM plug when "exploring" what's what, as you know what most of them are.

I've been trying to find a diagram for the JDM lights, which would really give you all the answers you need, without all this hassle, but haven't been successful. However, these seem to be custom made; you might be able to reach out to the seller and ask what the pin out is for the JDM side.
