Default How To: Wire Aftermarket LED DRL Fog Covers

How To: Wire Aftermarket LED DRL Fog Covers

This idea will work with any aftermarket LED DRL assuming certain conditions are true.

Basic Knowledge of DRL System

To understand this setup, you need to understand the fundamentals of how the DRL system works in the Crosstour.

The OEM DRL system in the Crosstour runs off of the High Beam Bulbs, so the key here is to understand when the High Beam + wire has power, and I'll simplify that to "DRL = ON" in the example below.

Here are the "Conditions" for the DRL system.

Car Off: DRL = Off
Car On, Low Beams Off: DRL = ON
Car On, Low Beams On: DRL = OFF
Car On, Low Beams On, High Beams On: DRL = ON

What my desired "ALL ON" look is like:

Car Off: DRL = Off
Car On, Low Beams Off: DRL = ON
Car On, Low Beams On: DRL = ON
Car On, Low Beams On, High Beams On: DRL = ON

Reason for Aftermarket DRL Kit

1: I do believe DRLs are a safety feature, especially worth it in the late afternoons when cars tend to blend into the background or when the sun is low enough to interfere with visuals.

2: When you run HID Kits in both High and Low Beams like I do, the High Beam HID does not act as a DRL because there's not enough power to ignite the bulb.

3: When you run LED Kits in the High Beam position, you will blind people in broad daylight because LEDs don't dim like OEM Halogens do.


Basic Knowledge of Aftermarket DRL Kit

I won't talk about the install of an Aftermarket DRL Kit, I had the shop do it and they wired it to the + Wire on the High Beam circuit, which gave me the OEM functionality.

What I will say is that this DRL kit has a control unite (relay) that turns the DRL LEDs on and off depending on the condition of the High beams... If your LED Kit doesn't have a relay, you must then also build a control relay so as to not over draw power from the Control Circuits (Low Beams).

The Key Point here is to understand that your DRL kit draws power directly from the battery, and requires a + Power to control (turn on / off) the system.

So the whole point of what I'm doing in this DIY is to build a relay to control the control relay of the DRL system...

Things You'll Need

How to build your Relay
  1. Take 1 of the 9005 and H11 Extensions (make sure you don't get them mixed up), cut and strip off the protective plastic shield.
  2. Take the Wire Taps and Connect the Relay Wires #85 to the Low Beam Black
  3. Take the Wire Taps and Connect the Relay Wires #86 to the Low Beam Red
  4. Take the Wire Taps and Connect the Relay Wires #87a to the High Beam Red
  5. Wrap all Taps with Electrical tape...

Optional:
I used Male / Female Flat Connectors on the Relay Wires #30 and 87 so that I can disconnect the relay system completely if I needed to do maintenance.

Installing the Relay:
  1. Connect the 9005 and H11 Extensions
  2. Connect the #30 Relay Cable to the LED DRL ACC Control Wire
  3. Connect the #87 to the Fan Relay via a 16-14 Gauge Wire Extension (again I used Male / Female connectors to make it detachable on both ends).
  4. Mount Relay: You can mount the relay anywhere you'd like using Zip Ties or Double Sided Mounting Tape...

They are from China via:

https://www.aliexpress.com

Type the search term: "Crosstour DRL" or Crosstour DRL fog", etc.

Make sure you find a reputable seller, a company, and not an individual, and has a history of many months on the site.

The first seller was an individual, and I never got the product or money back.
The store then disapeared.
The second seller I went to was a company dealing this kind of stuff and it was fine.

Can't you just hook the DRL LED lights to any switched 12v accessory source? I am sure they are low draw.

I think in theory yes. There is a Positive, Negative, and a Switch.

I just haven't spent the time testing it.

Love this mod - and *definitely* agree that increasing the active light profile in morning/late day conditions is a major safety feature.

Default Thank you!

Love it when someone take the time to explain a mod in detail, my friend. Thanks for posting!
