Kibble,
I found it, see teh screenshoot, it is just after you exit the last of the curves, take the opening and make a quick right after the trees, then follow the road down across the lake, then a hard left and continue up the path till you come to the opening with the trucks, make sure you save a couple of times. After the cut screen you will have to jump your truck over the gorge and when you land, then avoid the gas barrells and run through the cables to your right, then the cut screen takes over again.
Good Luck
