A client from Goldsboro contacted Adrenaline Autosound in Clayton about installing 2016 Jeep Grand Cherokee LED daytime running lights. We invited the client in for an initial consultation to discuss the installation and how he wanted the lighting to work. After discussing several control options for the lighting, the client approved our quotation and we scheduled an appointment to begin work.
OEM Switch Integration
We are fanatical about our work looking like it belongs in the vehicle. Adding a toggle or rocker switch to the interior of a vehicle clashes with its aesthetics. During the consultation, we looked at several places we could conceal a switch. Finally, we suggested repurposing the third HomeLink button to control the lights. The client confirmed that he’d never used this button, and if we could make it work, he loved the idea.
We removed the overhead panel and disassembled the circuit board. We soldered a wire onto the third HomeLink switch and added a pair of indicator LEDs above the HomeLink LED. After adding current-limiting resistors to the LED wires and protecting them with heat shrink tubing, we bundled the wiring with automotive-grade tesa cloth tape. The wiring is terminated with a pair of Molex quick disconnects to ensure the system remains serviceable at all times. Once reassembled, you can’t tell we made any modifications.
Jeep Grand Cherokee LED Control System
We ran the wiring down from the overhead console following the factory wire path and secured it along the way to prevent buzzes and rattles. With the wiring extended to behind the glove box, we created a panel to mount the three system control relays and a PAC TR7 module out of ABS plastic. The relay wire terminations are protected with heat-shrink tubing to keep the connections reliable. We added labels to the three relays to make any future service easy and efficient.
When the vehicle is started, the aftermarket running lights turn on automatically and the LED in the overhead control console illuminates in blue. If the driver wants to turn off the lights, he can tap the third HomeLink button. The indicator will turn red. The PAC TR7 module handles converting the pulsed input from the HomeLink button into a switched control for the lights.
The client returned to pick up his Grand Cherokee and was impressed with how we were able to integrate the Jeep Grand Cherokee LED lighting control into the vehicle. You can check out the video below to see the system in action.
