On the distributor, starting from the bottom left and going clockwise; it is 1-3-4-2. So bottom left is 1, top left is 3, top right is 4, and bottom right is 2.On the engine, look at the engine while looking towards the firewall. The far right cylinder is #1, and the rest are in order from there. So it will look like 4 3 2 1. #1 being closest to the timing belt, and #4 being closest to the transmission.
