    Hi all.

    Hoping someone can shed some light on this. Got a JDM EP3 pre facelift. Have a horn that isn’t working. Checked fuse 7 in the engine bay. That’s okay. Removed the front bumper to reveal that both horns have been removed for some reason.

    Found the plug for the horn on the N/S, tested for power when pressing the horn on the steering whee and no power is getting to the plug. I checked the opposite side but there isn’t a wire for the horn there.

    Further digging around I found this harness that has been cut and stuffed into the O/S/F wing. It is routed on the drivers side but have no idea what it is for. A quick test of the wires and all of them were dead. A7DB59D0-0C60-4E51-A861-374D6723F389.jpeg

    Can any tell me what this part of the harness is for? Is one of them wires for the horn? And what else I can check for the horn not working.

    Any help appreciated. Thanks.

    Very strange, The japanese have a tendency to fit aftermarket horns and these may have been removed or originals have been damaged at some point.

    The wiring looks aftermarket to me though. I know the JDM EP3 uses the same ECU pin-out as the DC5, Unsure about fusebox and harness etc... if it's the same as a UKDM which it probably is, getting parts from a UK car would probably be the best idea. OEM steering wheel in car?

    Yeh, OEM MOMO steering wheel fitted. I was thinking the originals have been taken out but it would of made sense to fit a different horn in its place. However, there isn’t so this is why I’m scratching my head with it. :angry2:

    I have been told (and have acquired a none cut, full body loom) a UKDM harness is the same as the JDM ones. The seller told me that nothing should be routed outside of the engine bay unless someone has attamepted a wire tuck or something similar. Now it’s a matter of removing the wing and tracing back where them wires go. Wish me luck:x:
