Product Information: JK-HARNESS for JEEP

The JK-HARNESS is a wiring harness kit designed for Jeep JK and JKU models. The kit includes a series of screws, nuts, and other hardware required for installation. It also comes with a SQBass Rack/Bracket and under seat amp, along with an 8mm screw and nuts. The installation of mobile audio and video components requires mechanical and electrical experience. Therefore, it is recommended to consult an authorized dealer for professional installation service.

Product Usage Instructions:

1. Disconnect the negative post (Ground) of the battery before starting the installation to avoid airbag coding and malfunctions, code module malfunction, or any electrical issues.
2. To install the SQBass Rack/Bracket, start by removing the bolts of the Driver seat using the 18mm socket with an impact wrench tool. Remove the belt screw from the seat using a T40 socket. Now, remove the seat from the Jeep and put it on this position for easy access under the seat.
3. Locate the Connector holder plate and remove it using the clip remover for the connector and the T27 socket for the two screws that hold it. Relocate this wiring under the seat to one side using the same pin spots as you can see in the picture.
4. Locate the SQBASS Bracket A and secure it on the SQBASS using the B screws supplied and tight them just enough but not too hard (Screw can break easily). Locate the SQBASS under the seat and use a pair of A screws and secure the bracket but do not tighten them yet, then using the B screws secure the other side of the SQBASS to the bracket B as you can see in the picture.
5. Install the amplifiers to the Amp Rack using the supplied C screws, tight them well using a 7mm socket and the #2 Philips screwdriver. Check the position of the amp as you can see in the picture for easy wiring access, before putting this under the seat you can go ahead and install the speaker and amplifier wiring, this is an easy way to access the terminals.
6. Slide in the bracket into the gap between the SQBASS bracket and the seat bracket and tighten up all the screws using a 10mm socket with the impact wrench.
7. Connect all the wires for the SQBASS and the amplifiers, then get ready to put back the seat into the Jeep and route the rest of the wiring: (1) Ground and to the engine bay for battery power, (2) for the Radio in the Dashboard, (3) to the roof soundbar.
8. For radio side installation using Factory OEM Radio (Without RCA pre-output), connect the DS18 T-Harness connector between the factory radio unit and the radio harness.
