I've looked through a part diagrams and the Toyota service manual, neither of them detail the orientation. When I did my 5-speed swap I don't remember there being any confusion which way the clip went on. I believe it is Option 1, only because it wraps around the throw-out bearing, seems more secure that way. The clutch fork needs to rotate slightly on the throw-out bearing when it engages and disengages, so try that with both orientations and tug on it a bit and see how secure it is. Good luck.
