Brent,
Pete's diagram is correct. The plug wires are part of the coil assembly.
My question is, why do the plug wires need replacing? If the insulation is intact, the core is wire, and is durable. The plug connector can be replaced.
It may be possible to buy the entire coil assembly. I would check with a Evinrude dealer.
