The coils have the numbers on them but the firing order is 146325 and the original wires have the numbers on them but you might have had them replaced so they might not. The 1 cylinder is the cyl closest to the front of the engine and the sides go 135 on that side and 246 on the other side. Usually the plugs to the front of the vehcile are 246.
