Information about marine electrical wiring and common color codes used in Boston Whaler boat is available in the REFERENCE section. This article has just been updated to include information about color codes seen on OMC outboard motors (JOHNSON and EVINRUDE brands).

Jim - From Mercurymarine.com, you can pick up the Mercury color coding. Some of it looks similar to the OMC colors.
I think the Japanese motors use a different color code.

Concerning the E-TEC key swItch wiring colors and designations, what does "Bootstrap" refer to on the black-orange wire? Thank you,

At the E-TEC end of the wiring MWS harness connector, pin 6 is connected to a black/orange conductor which runs to pin 8 of J1-A on the EMM. In previous models this position of the MWS harness connector was associated with the CHOKE circuit and used a VIOLET with WHITE STRIPE conductor. The E-TEC does not use a CHOKE in starting.
The term "bootstrap" is used in electrical circuits in the sense conveyed in the old expression, "pulling oneself up by one's bookstraps." In the E-TEC the bootstrap circuit is associated with re-programming of the EMM, and a specialized adaptor tool is used in conjunction with this circuit. This circuit is not used in normal operation of the engine.
