Update:
Fog Lights:
While removing this harness from the car, I found that part of the harness runs under the passenger seat. This part of the harness goes to the fog light and firm ride switches in the center console. In order to maintain the fog light functionality, I unwrapped the harness between the fog light switch connector and the two connectors by the ECU. I then removed the needed wires. The fog light switch has three wires going to it. One is the power wire going to the switch (when low beams are on), another is power going to the fog lights, and the third wire is the ground to make the light inside the switch work. I was able to remove all the other wires out of the two connectors by the ECU without cutting the harness. I used a small flat piece of metal (one side of a pair of tweezers), pushing in from the wire side of the connector to release the locking tab inside. I also kept the firm ride switch connector and its two wires in case I wanted to re-purpose that switch in the future. The two wires going to the firm ride switch go all the way back to the ride control computer, so i just cut those two wires where they joined the main harness. That should make it easier to re-use the firm ride switch later.
Variable Assisted Power Steering:
I forgot that (on the SC and XR7 models) the ride control computer also controls the EVO solenoid on the power steering pump. So deleting this harness will remove that functionality. My understanding is that this feature makes it easier to steer at low speeds and tightens up steering at higher speeds. I drove the car for over an hour on the back roads to see if I could tell a difference... and either I am oblivious or something, but I didn't really notice anything different.
ABS light:
The ABS light went out when I disconnected those two connectors by the ecu. This makes sense, but I did not expect that. Now I don't have to pull the cluster to remove the bulb!
