Actually two questions..

what is the cable the goes to the unit on the passengerside of the vehicle? Please dont tell me this is our drive by wire setup..

Next, i Noticed a lonely plug around center on the firewall, about the size of a nickle. I pushed it in and it gave, so i used my pliers and put it back in its original spot. Is this the spot where the clutch cable would go if i were to have a manual?

Would this be a good spot for a powerwire? (amp)

1. Yes, it's part of the DBW setup. What's wrong with it?

2. Not sure which plug you are talking about, but there's no clutch cable. MT uses hydraulic clutch system.

I would think DBW would completely eliminate cables.

My toyota, uses a hydraulic clutch two, but there is a cable up the the hydraulic piston, which is attached to the transmission.

The DBW systems needs to know how much pedal you are pressing. What you see there is the Accelerator Position Sensor and it sends the signals to the ECU for processing. The ECU then sends the signal to the throttle body motor to move the throttle plate.

A hydraulic clutch system has no cables but it uses hydraulic lines to send hydrulic fluid from the clutch master cylinder to the slave cylinder on the transmission bell housing.

If you look at the pic below, item #8 is the clutch master cylinder which connects to the clutch pedal. The fluid in the fluid reservoir is sent to the clutch master cylinder via a hose # 25. Then the fluid is sent to the clutch slave cylinder via hydraulic lines #17 and #24. Then finally to the slave cylinder #10. This is the standard hydraulic clutch system design for many, many years.
