I've got to be missing something. I installed the DRL relay in the passenger compartment fuse panel, but no DRL. Do I need to install a fuse for the DRL's?

Sorry everyone it seems the "enable DRLs" has been removed as one of the features found in the Starscan. As it stands right now it no longer is a function that can be turned on using the Starscan (Chrysler's computer scanner). Maybe they'll put it back into programming in the future or release a software update that can enable the daytime running lights.
Operation of the Nitro DRL's (Daytime Running Lights) is a function that occurs via the CAN bus. There is not external module for DRL's and is a function that is performed within the TIPM (Totatlly Integrated Power Module.)
Vehicles equipped with the Daytime Running Lamps (DRL) feature illuminate the high beam filament of both headlamp bulbs at a reduced intensity when the engine is running, the parking brake is released, the headlamps are turned OFF, and the optional automatic transmission gear selector lever is in any position except PARK. The park lamps may be ON or OFF for DRL to operate. For vehicles with a manual transmission, the DRL will operate in any transmission gear selector lever position. The TIPM must be programmed appropriately for this feature to be enabled.
Once enabled, anytime the TIPM receives electronic messages over the CAN data bus from the Powertrain Control Module (PCM) indicating the engine is running, from the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) indicating the status of the left (lighting) multi-function switch is in any position except headlamps ON and the parking brake lever is released, and from the Transmission Control Module (TCM) indicating the automatic transmission gear selector lever is in any position except PARK, the TIPM provides a pulse width modulated voltage output to the headlamp high beam bulb filaments through high side drivers on the right and left high beam feed circuits to produce illumination at a reduced intensity.
The service manager at my dealer called me back yesterday.
He said that they had originally thought it was in the computer under "new vehicle prep" to turn on running lights, but after looking at mine, the feature wasn't there.
They called the Jeep tech support folks, who told them that the feature had been removed in the 08 Liberty. They did tell them that a lot of insurance companies are offering discounts if you have daytime running lights, so they've gotten a lot of requests for it to be turned on. He says he thinks they will allow them to be turned on with a flash upgrade to the computer.
Can you tell us where the sensor is located?
Is this still the case?It doesn't seem to be possible. Reposted on another Jeep Forum, originally on a Dodge Nitro site:
And this is actually regarding a KK....
Bummer. I'll drive over to my mechaninc, see if he can look into the computer and see if there has been any changes. But it looks like I'll be visiting Amazon to try to find lights and relays and just add my own. Really if I could get the auto-on feature on our KK to actually turn on when it should, I wouldn't mess with the DRL.
I know of no one who has been able to active the factory DRL feature by changing a setting in the computer. It's much easier to just add your own lights.Is this still the case?
