Note: For carburetor applications this connector is cut off and the Brown/Yellow is not used. For EFI applications,

this connects to the number one coil connector.

*Note: The harness is set up for use on a SOHC engine. DOHC engines use coils with reversed polarity. In these

applications, the location of two coil wires needs to be swapped in each connector.
