Installing tow package on 2006 w/KDSS
My 2006 GX470 did not have factory delivered towing components installed. I believe it was because the car had KDSS.
Here is what I ended up buying/installing:
Curt Trailer Hitch CT13445
Relay 90987-0205 $50 installed in engine compartment –Towing Tail Relay
Relay 90986-0205 $50 installed in engine compartment – Battery Chg. Relay
Towing converter
Relay 81985-60021 $30 installed in rear of vehicle behind left rear panel – plug and play
Brake Controller
Harness Trailer Brake Jumper Harness aka Trailer Brake Harness Wire -bought off EBay for $10. Plugs in under dash on drivers side of car to tie in the brake controller. The factory number is 82132-60110. This part is available from Lexus or Toyota and has five wires. When I connected to the Curt controller I only used four wires as the Curt only has four wires.
Note: The Curt controller below that I bought from ramrunner.com on EBay included a harness. This harness has four wires and is the proper plug configuration. I did not use as I had the factory harness. However since the curt controller only has four wires I ended up only using four of the wires of the factory harness and this harness should work. I believe the part number is I-2136P.
Brake Controller Curt I-1725 $60 Brake controller that included harness. A lot of brake controllers will work.
Trailer Plug socket Draw-Tite 20137 $60 This is the plug assembly to plug in the trailer wiring to at the back of the car.
This was the biggest issue for me. The Draw-Tite has the proper shaped plugs to match up to the plugs that were there for the taking in the back of t he car by the spare. The problem is the Draw-Tite has female plugs and the Lexus plugs are also female. I had to cut off the plugs and hard wire. I found the time and effort to be frustrating. Took about two hours, had to remove the spare to get better access, lie on my back and solder the wires together.
I believe Lexus and Toyota have this part and would assume the plugs are males to match with the females on the car currently. I believe it is over $150 dollars, but I don’t know this for sure. It may have been worth it to buy a plug and play. I don’t know the number of the part.
To recap: Trailer Hitch assembly, Two engine compartment relays, One relay in back of car, harness for brake controller, brake controller and rear plug.
