If you want them to come on with the ignition, try tapping into one of the thick black/yellow wires in the back of your fuse panel, if you want them to come on with the sidelights, I believe pin 8 (-) and pin 10 (+) on the T10 connector on the back of your headlights could work, or find out which wire supplies the sidelights on the back of the lighting switch. If you want to be sure, make your self a test lamp to use instead of forking out for a multi meter (2 bits of wire attached to a bulb) to check the feed before you wire your lights in. Please don't blame me if stuff sets on fire and please don't use scotch locks, they're the devil!
