    Default S2K headlight wiring

    I am using S2K engine and wiring harness but am not using the S2K headlights. trying to connect standard Hi/Lo connection to wiring harness. Looking at schematics, the S2K harness relies on their headlight DRL module to activate hi beams. Has anyone made this work on their car? The current plug in will activate low beams only.

    Sorry, I wired the headlights directly to a HI/LO switch on the dash, didn't use the harness.

    Discovered part of the issue was the car and part of harness was from Canada, which requires Daylight Running lights. Hi beams were putting out 6 volts to hi beams to turn them on when driving. Finally just added a new relay and activated from the high beam switch on column.
