I actually posted a how-to on
disabling the DRL in the Canadian forum.
Anyways, I just got the Helms service manual today and took a quick look. According to the manual, the system is above the gas pedal area after you remove the driver's dashboard lower cover. If you can find a loose 14-pin harness in that area on the US spec Fit, there might be hope. You could them possible try to plug in a factory fit DRL module, and add the 7.5A fuse in #8, and 10A fuse in #18.
