Manufacturer InstructionsInstallation of a Wiring Harness on a 1999 Jeep Grand Cherokee
Today we are going to be installing wiring harness part number 118369 on a 1999 Jeep Grand Cherokee. We are inside the rear of the vehicle, and we are going to go ahead and locate the connector for the wiring harness. The Grand Cherokee actually has a separate port where our wiring harness is going to plug into. And it is actually located on the drivers side, right here behind this interior panel that sits right about - right in here. So, we are going to need to remove this, and to do so we are going to need to take out a few screws. Take out the two screws that are holding down the tie-down hooks and then we want to take out the one screw that is holding the drivers side of the rear threshold piece. I am just going to come in and start here at the rear portion. I am just going to take a regular, flat-bladed screwdriver and just it here behind the panel. And just gently pry back until you hear the clips release.
What I am going to do is pull back this black cover and expose the green plug, which is where our harness is going to plug into. I am just going to take our harness and plug it into the port here, and then you just want to slide the red clip from the bottom side up the top, and that locks it in. And then we just want to take our Modulite box, which is part of our harness here, and you can see on the back side of it we have got some double-sided tape. And I am just going to remove that and I am just going to stick that right here to the back side. And then we are just going to take our 4-pole harness - and this is actually going to stay inside the vehicle here - and I am just going to zip-tie it here with the provided zip-tie from the installation kit. And that is about it for the installation portion. And we are just going to go ahead and put the interior panel back together. This will conclude the installation of wiring harness part number 118369 on a 1999 Jeep Grand Cherokee.
