How To Add Full-Time DRL (Daytime Running Lights) to the JL Sport

For those of you with a JL Sport, here’s a great DIY writeup on wiring full-time DRLs (daytime running lights) with active turn signal switchbacks on your headlights & fenders. This will allow you to use your auto-headlight function full time, so no need to switch your parking light on & off to activate DRLs.

The result is great added functionality and safety to your JL Sport with no error codes or hyperflashing.
