My clutch pedal is soft and on the floor after forward gear cable connector replaced
2001 911 turbo. I replaced forward gears cable connector to bottom of stick and now have no clutch pedal. Pedal is around 1” from floor of vehicle. Chf115 hydraulic fluid container is almost empty. Could this be the reason?

Whoa...wait a minute. There is no CHF115, but there is CHF11S, which is the power steering fluid. The power steering fluid reservoir is in the engine bay on the belt driven power steering pump, and has no impact on the clutch pedal. Then there is the brake fluid reservoir in the frunk (front trunk), which is shared by the brake system and clutch system. Please note the difference...one has power steering fluid and one has brake fluid.
The shared reservoir in the frunk with brake fluid does impact the clutch operation. If it is low on fluid air bubbles will get in system and the pedal will go soft.

OP, go to Pelicanparts.com and search the 996 section tech article:
Replacing Clutch Hydraulics on the Porsche 911 Carrera
Good place to start. Photos there should help. Good hunting.

Dbjoe, op has a turbo. Chf11s lives in both power clutch reservoir and power steering reservoir.
OP DON’T put regular brake fluid in your little clutch reservoir or CHF11S in your separate brake reservoir.
First check your power steering reservoir to make sure it is at the right level.
If your clutch is on the floor and the clutch reservoir is low you probably have a leak that has introduced air into the system.
Turbos have a power clutch with basically two systems. Low pressure between the clutch master cylinder and one side of the slave cylinder on the transmission and a high pressure system between the power steering and the other side of the slave on the transmission.
The best way to bleed it is a power bleeder. You can also pump open bleeder close bleeder pump etc same as brake bleeding except you will have to pull the pedal up each time. The power steering/high pressure side bleeds itself after about 10 pumps with the engine running.
DONT GET CHF11S on the coolant lines they will swell and fail. Rinse immediately if you do.

The more common failure is when the valve on the high pressure side of the slave starts to fail allowing the fluid to migrate into the low pressure side. This causes the small reservoir to overflow and the power steering pump to run out of fluid.
Last year I had to change my failed slave cylinder. This year my master failed and leaked on my foot. They can both be done on jack stands. The master is actually inside the car but you still need to bleed at the slave. If you are doing the master take the seat out, it will save time and pain.
