Today on this 2007 Lexus RX350 we are going to be installing the 4-pole harness part number 18002. The Lexus that we are going to show you today has a unique situation to it. On our website we indicate the wiring for the Lexus is going to be modulite part number 119176. This particular Lexus does have a factory installed tow package that we are going to be able to tap into so we are going to show you how to locate that. The port is located in the rear cargo area of the vehicle underneath the flooring over on the driver side. We are going to need to remove most of this interior section. There is a particular order of operations that we need to abide by to get all of the components out. 00:38
We are going to start by removing the forward most cargo door. We need to pull back the facing at the front section first. There are push rivets that are holding that in place so just pull it up. We need to unscrew the hinges that are holding the flooring into place. There is one screw per side for these hinges. We next remove the forward most cargo storage area. There are two push rivets holding this into position. One on the driver side and one on the passenger side. We are going to be using a rivet removal tool. We need to slide it underneath and just pry it up. 01:11
Next we are going to remove the front storage compartment. To access it we need to release the two coverings and there are buttons at the rear threshold to do that. Again, we have got two push rivets holding it in place. One on the driver side and one on the passenger side. Next we will remove the driver side floor covering and there are actually four bolts holding it into position, two here at the rear side and two at the forward side. Next we will remove the rear threshold piece. There are two push pins that are holding this into position. One on the driver and one on the passenger side. When removing the threshold piece you need to watch the releases for the cargo buttons. Make sure you clear the releases for the cargo doors. When you get the threshold piece to release you need to press these in. Finally we want to remove the driver side storage compartment. We have got two fasteners holding it in position. One push pin here and one here at the inside of the cargo area. 02:22
With all of those components removed, if we look at the main wiring harness feeding the tail light assembly on the driver side, there is a port located right here and that is our tow package port that we are going to be tapping into. Unfortunately this time the manufacturers do not offer an after market plug-in for this port. So what we are going to do is cut this end off and we are going to wire our wiring harness directly into it. Before cutting the end off I am going to remove the fuses activating our tow package so that we do not shorten anything when we cut the wires. You can locate this fuse underneath the hood in our accessory fuse box. If you remove the lid and look at the top side, it is labeled towing 30 amp fuse. We will put that back in when we are finished wiring in our 4-pole. Then back at the port we will cut the wires. The 4-pole harness comes with scotch locks to make our connections with. However I am going to use some standard butt connectors. We tested previously to find out which wires carry which function. The green is our right turn, right brake signal. Yellow is our left turn, left brake signal. The blue wire is our running light lead and the white is the ground. It is pretty similar to the wires that we have got on our 4-pole harness. The white is our ground, the yellow is our left turn, left brake. Green right turn, right brake, and the brown is our running light lead. 03:52
We want to strip back some of the jacketing on each one of the wires. With our wiring stripped back we just want to apply the butt connector. We will the wire into one end and then we will crimp that down. Take the adjoining wire and slide it in and crimp it down as well. Then we just want to tape up those connections. Then for storage of the 4-pole we have two options. We recommend that you leave it inside the vehicle. Store it in the storage compartment over here and then just pull it out the rear cargo door whenever you want to use it. However if you do need it underneath the vehicle permanently there is a grommet there right below the connector. You can just put a splice in that, route the 4-pole through there and then you can leave it underneath the vehicle permanently. From there we just want to put our fuse back into position and reinstall our flooring and then our installation will be complete. With the interior reinstalled we will show you how you can store your 4-pole. When you want to use it again just pull it out the rear door and you can close the door on it. You do not have to worry about it being pinched. The weather stripping at the rear will prevent that from happening. You can see I can still move it side to side freely. With that, that will conclude the installation of 4-pole part number 18002 on a 2007 Lexus RX350.
