Thanks for the reply.
Subaru’s dimmer system really is an odd one.
Knowing that the factory footwell lighting kit dims with the instruments I looked it up.
It appears that it ties into the hazard lights button and clock circuit.
Looking at pictures of it, the wires don’t make any sense. There appears to be 3 wires going to each led harness.
Too bad it costs so much or I would buy it for the harness.
