Subaru WRX: How to Install LED DRL Wiring

This guide is to show how to install the daytime running light wiring in a 2012-up Subaru WRX. This is especially important because if we directly install the LED bulbs on 2012-up Subaru WRX high beam daytime running lights, the LED bulbs will not fully light up. The new LED bulbs for daytime running light is a great addition to make your stock Subaru WRX stand out.

1. Remove the plastic cover to access the bulbs underneath.

Connect #1 to battery positive. Always connect #1 last.
