Compass mirror
Front accessory power supply socket
Body integrated module
TCM
Rear 12 V accessory relay
Remote control mirror switch
Intercooler water spray switch
Intercooler water spray timer


I just tried running the Red Molex wire directly to the battery. No change.

What I really cannot figure out is why the blower motor relay has any authority over HFS-3 at all? Currently, power being taken directly from the battery, the grounds are bolted to the kick-panel bracket and I snipped the illumination wire is completely disconnected, (I wanted to see if it changed anything, it did not).

As soon as I unplug the blower motor relay, the system turns off! I have all the diagrams for all of these things I can simply cannot find anything that they have in common. Especially now that its hooked up directly to source voltage.
