Ok. Here's a pic of the pin you need to bend (or remove) to disable Daytime Running Lights on Galants (and Eclipses). This module (known as the Front ECU Module) is under the hood, inside the fuse box, on the driver side. If you're not sure, look in the manual. Remove the Front ECU, and open it carefully using a flat screwdriver. You can "pop" the white snaps on the black metal part (it's a chip cooler) to completely access the pins, and remove the bottom cover (black plastic). Bend the second last (or 1st) of the SMALL pin connector. Re-assemble, and voila!
P.S. Please be careful. And do not sue me if something happens. You're a grown up, assume the consequences. :P Click Here to view the modified ECU
