On the fox's it's by the distributor I think, on ours it's where Scott said, to the left of the intake filter box, kind of in the fender, looks like a small grey fuse thing. However, I've never had to get on the ground check my timing, there is a pointy steel bracket right about 11 o-clock on top of the balancer which is the pointer you use. It's alittle hard to see, you have to point the timing light just right down there to get it, so take off your tie!
