ChevyBeat 28 Posted June 29, 2018 Share Posted June 29, 2018 Guys, I want to install DRL on my 2010 LS (M300 similar to US 2013). I want the function as follows: 1. When ignition is turned ON, then only DRL have to come up, so no load on battery. 2. When parking or headlight turned ON, DRL must be off. I worked with relays and partly got it theoretically. By tapping ignition line from key switch can latch relay for DRL and a tap from illumination line will cut off supply to DRL relay when parking/headlight is turned ON. Now, issue point is when DRL are ON and parking light are turned ON, it turn off DRL as expected but if parking light are turned OFF after that (assume someone turn them by mistake while engine still running), DRL doesn't come ON again. So, is there any direct point available which can give engine running feedback, as I don't prefer too much tapping OEM lines? Link to post Share on other sites
