Ok, so here's what I'd like to do:
I'd like to wire up a little light or something in one of the empty pannels near the steering wheel, and have it light up when the radiator fan is on. Now, I'm looking at the circuit diagram in the service manual (Page 10-13), and it's confusing me slightly, so I'm hoping someone out there can answer a few things for me.
First off, the fact that the A/C and Radiator Fan relays share the same wire (Black/Yellow) for the control side of the relay is confusing me a bit. Now, I see that it branches off to the A/C system before the relays, and that makes sense, but as I follow it along, as it comes out of the relays as the Green/White wire, it goes into the ECM, and then to the radiator switch, then to ground. Now, does this mean that the AC condensor fan only turns on when the radiator fan switch is closed? Also, why does it go into the ECM before the radiator fan switch? I would think it would make more sense for it to get the reading from it afterwords. Lastly, let's say I wanted to have this light getting 12v off of an accessory position wire, then have the circuit close, thus grounding it, to turn it on. Would I just run my ground wire to where the Green/White wire goes to the radiator fan switch (pin #2), or is there an easier way?

If I worded any of this poorly or wasn't clear on something, I'll be more than happy to try and rephrase. Thanks in advance.
