I don\'t think it has wiring provided in the factory for the tow package either. Looking at the schematics, they appear to be different with no provision for connections. The aftermarket have a wide variety of tow packages available which are simple enough to install if you ability.
Threr is one which you have to drill a large hole in the rear bumper to fit the receiving end of the connector. This is designed so that a wide selection of adaptors can be plugged into it. The adaptors are designed to fit the fixture in the bumper and the other end is shaped to plug into what ever connector you are towing. You will find this knid of fixture on nearly any factory package.. (NO WIRES DANGLING UNDER THE VEHICLE.) additionally, when not in use, there is a spring loaded cover which closes over the fixture to keep contaminants from entering Although I am a Nissan Master techniton, I chose a long wheel base 1 ton long wheel base cab and chassis Toyota with a 3.0 V-6 which I opened the back of the cab and installed a sleeper. Then built a flatbed with removable sides. I use this to pull my Nissan 300Z race Car. I have one of these fixtures on my truck because I don\'t always use the same trailer and the connectors to the trailer for the lights and electric brakes are different. The kits come with a controler for the electric brakes which you can mount where ever you wish and the controller has adjustments to control sensitivity of the trailer brakes so you can adjust the trailer to stop with the truck about the same time instead of wearing out your brakes from the extra load. With my Toyota loades with an extra engine, transmission and diff. Air compressor. Generator. Tool box, pop up tent, oils and other fluids and other misc Items. Between the trailer, the truck and it\'s load it grosses out at 11,800 lbs.When we go to Texas world speed way, we take 45 south where where there are very few cops. We cruise at 80-85 mph in the truck without a problem If the trailer brakes don\'t work, it would take me a significant time to stop because my truck is rated for 9,500 lbs.I run the living piss out of it and it has given me no problems at all/Hmm How did I get on the subject of my Toyota flatbed? OH, it\'s because I use the trailer brake setup I described which has been flawless. There are places that specialize in selling truck accesories only. From camper top and wheels to a variety of tow packages.Check them out. Good luck..
just buy another 7 pin connecter and connect the wires to the same wires that your existing plug is conneced to. or just drill a hole throgh floor of box and drop your fifth wheel cable through hole and plug into the one you have. whoever complained about the cable over the tailgate has to much time on there hands. what if you take the tailgate off what then?
there is a standard tow bar and a 2000kg for genuine tow bars
you need to remove both tail lights,the bumper bar and reinforcement bracket, spare wheel and exhaust hangars on rear mufflers, remove the tie down bracket on LHS chassis rail(dont need this or the bolts that hold it on), so you can then bolt in place either of the 2 tow bars.
genuine wiring patch harness for trailer plug is my suggestion since its plug straight into vehicle and interfaces with vehicle, goes in right hand rear compartment remove lid then remove box, interface connector for trailer harness is there.
instructions can be printed out from dealers if you ask
some new kits dont come with instructions in kits because information is on dealer computers
there is a template to print out to cut hole in bumper bar for tounge area of tow bar, uses centre square dimple in bar but its a bit wider.
You have got 7 pin trailer connector that was included in the optional trailer tow package. This trailer tow package also includes an electric trailer brake wiring provision that terminates at a connector located on top of the large body harness connection under the instrument panel to the left of the break pedal, as well as an electric trailer brake pigtail harness and an instruction card that are stored in the glove box when the vehicle is shipped from the factory. You will need to add an electric brake controller of your choice that will plug-in to the harness and that will also give you power on your auxiliary circuit.
This is the tow vehicle end. The brown wire ( #6 terminal) is the one to concentrate on. It must have a bad connection either in plug at bumper or wherever mounted, or follow it back toward front of vehicle, and will likely have a connector just behind bumper area, or up near frame as well. Best thing is to use a test light ($5-$10) and probe toward front until you get power showing, then work back to plug to isolate. Begin by checking terminal at plug with blinker on, if no flashing of test light, find brown wire on back of plug & test there, and keep going toward front of truck, especially concentrate on connection areas. Understand? If not, get back to me
