CDI Electronics 413-3602 Wiring Harness, Replaces 583602, Fits 1988 Johnson/Evinrude 40-50 HP 2 Cyl Round Plug

The CDI Electronics 413-3602 is a 2-cylinder wiring harness built for 1988 Johnson/Evinrude Round Plug outboards. It carries the ignition and charging circuits between the powerhead and the engine's electrical components, giving you a direct, factory-fit replacement when an original harness has cracked insulation, corroded terminals, or intermittent connections that cause hard starting, stalling, or erratic gauge readings. Made with copper conductors for reliable current flow and long service life, this harness is engineered by CDI Electronics as a cost-effective alternative to OEM-supplied wiring while matching factory fit and function.

This harness fits Johnson/Evinrude 1988 40 HP, 45 HP, 48 HP, and 50 HP engines equipped with a Round Plug connector. It replaces OMC part number 583602, so it drops into place using the same connector and routing as the original equipment harness.
