I pulled the battery tray today and got looking at the mounts behind it. I have the deluxe heater controls and the engine compartment side seems to agree with that (green bolts->heater core, red bolts->blower motor).
Based on the FAM and pictures online, I think the heater hose locations are correct, but I cannot figure out what those other two holes would have been for.
Anyone have any ideas? At this point I am planning to pull the heater core to clean/test it and I will probably just seal those extra holes while it is out.
