mercruiser 470 spark plug configuration?

[cclements716]

My brother messed with my spark plug wires and mixed them all up. Does anyone have a picture of how it should be. Its an 88 Mercruiser 3.7L (470).

the shortest one should go to #1, the longest to #4 once you locate TDC for #1 cylinder.
firing order is 1,3,4,2
