So you wanna take the first right, right again, then left. Carry on that for 175km or so, before turning left, another right and you'll be good. Alternatively you can go right then left, and I'll see you in a couple of hours time…
Ahh, 'wrong' is relative: At least the first time I rode the descent I got to appreciate the views and the morning sun. For the second run, ~20 hours later it had all gone dark.
