Yup, any US vehicle coming up here needs DRL to pass inspection.
Last time we were getting a car through, and of course every thing was last minute, my buddy installed them in about 7 min. He's a car electronics wiz and apparently Honda Odessy is very easy to do, mind you this was connectors stuck in with fuses and the relay was tucked under the fuse box. LOL does the car have DRL.... Yes... Good enough.
Simple way.
Wire a relay in to your IGN wire and use it to give a signal to the head light relay, or switch. Since you are using a relay you can make the sending signal positive or negative.
