This post will focus on how to wire the Turn Signal / Marker Lights that come with your ARB Bumper. This will be done on my 2008 4Runner Sport Edition with Daytime Running Lights DRL).

1. Mount the ARB lights into your bumper.
2. Remove the Plastic Hood Trim cover.
3. Remove your headlight (3 tops screws and 1 sneaky hidden side fender screw, all 10mm).
4. Unplug your headlight and remove.
5. Locate the 3 pin grey connector that has 3 wires coming from it on the truck. Here is where the meat starts.
6. Find and install a suitable ground for each ARB Turn Signal / Marker Lamp.

7. Tap into the parking lamp and turn signal/DRL. See attached picture.

The Driver's side turn signal/DRL is Red w/ black stripe. The Passenger's side is Red w/ yellow stripe.

The Parking Lamps which come on when you turn your headlights on are Green for both sides.

*Warning; some people have reported the DRL which stay on all the time have caused their housings or lenses to melt. Consider installing CANBUS LED's for the 1156 bulb. If you buy cheaper 1156 LED bulbs without CANBUS your turn signals will flash fast as if there was a dead bulb.

8. Connectors: What does ARB use? Their Turn Signal / Marker Light uses a 3 pin "Sumitomo Type 250"

I used the "ET - ETN - Armlock Type - CN(B)- 250 Connectors" from Cycleterminal.com. You have to buy the connector housing and terminals.

I use a cheap "GM Delphi Weatherpack Crimper Tool" which goes for about $20 instead of the real expensive ratcheting type crimpers. Buy extra terminals if you don't have experience with connectors or bypass the ARB connector with your own home preference.

Materials:
Connector housing and Terminals
Wire Crimper
Electrical Tape (I prefer TESA Tape)
Butt Connectors for splicing into factory wiring
Automotive GXL Wire 12 AWG (don't use cheap wire!)

NOTES:
Headlight(w/ daytime running light)
* This system is designed to automatically activate the turn signal lights during the daytime to keep the car highly visible to
other vehicles. This system is controlled by the body ECU.
This system makes use of the turn signal lights as daytime running lights.
For this reason, when the turn signal lights are operated, the daytime running lights function is interrupted momentarily,
which, however, will be brought back into operation as soon as the turn signal is switched off.

Tail light relay trips the 10A TAIL FUSE powers your Front Parking Lights.

15A TURN HAZARD FUSE powers your Daytime Running Lights (DRL) and your Turn Signals. The DRL Relay/Turn Signal Flasher Relay tells your headlights when to have the DRL on and when to flash it when you turn on the turn signal.
