Hello, I am trying to find the circuit diagram (Not the wiring diagram) for the instrument cluster circuit board for the 2003 forester. If anyone can assist, It would be appreciated. Thank you.

@Marco_Aasterud may I ask what specifically you're looking for that's not on the wiring diagram?

Do you have the combination meter wiring diagram, which is combination of wiring + block diagram?

This is what I have, but I need the diagram that tells me the information about the power of the different little resistors, chips and the little parts. Kinda like a schematic.

@Marco_Aasterud I'm afraid that's as detailed as Subaru provides. As manufacturers say, "no user serviceable parts". If it doesn't work, replace it...

What are you trying to do that requires a detailed circuit diagram?

Unpublished specifications are a known drawback of those marvelous sealed boxes. Not mod-friendly, especially when current drive specs are involved. A solid state relay can sometimes be helpful when attempting to add to a basic on/off circuit, replacing the original direct connection. Beware of inductive kick if attempting to use regular relays.

When altering a circuit that drives bulbs, compute the load that the stock bulbs represent, and never exceed that. And cross your fingers.

We have seen reports here of people blowing the drive transistors in the boxes by exceeding the original load.
