Hook it up as Panko described (you can get a short spark lead when you get the timing light).You read the timing on the crank pulley (big one down the bottom of the front of the engine). There is a set of 7 marks at 5 deg increments, which move from driver side to passenger side (L->R as you stand looking into the engine bay). The last mark (left-most) is TDC (Top Dead Centre). Each time the coil fires on the #1 cylinder, the timing light will flash its light. The flash will "stop" the crank pulley so you can read which mark is aligned with the pointer located on the crank case cover. You want 15 deg BTDC (Before TDC), which should be the 4th mark (from either end).
