Question about 2007 Toyota Tacoma

1 Answer

2007 Tacoma Tail light problem.

I have a 07 Tacoma that I have a trailer hitch put on. It has a 4 pin flat connector that is converted to 7 pin to connect to my Coleman camper.
When I connected it, all the lights worked fine. Later when I was towing, I notice the trailer running lights were not on so I inspected the lights and found that my turn and brake lights work fine, but the trailer and Tacoma tail lights did not. Even when I unhook the trailer the rear running lights on the Tacoma do not come on.

Check the taillamp fuse on the truck. If it is blown, you either have a short in the wiring of the camper, or the 7 pin inverter box on the camper.

Yes, you need the other wires to provide the trailer with battery voltage. If the trailer has trailer brakes, you should have an RV mechanic wire up the connector so the brakes on the trailer operate from the Ford.

I have a 1999 F250 Super Duty Lariat Super Cab 7.3L diesel.The wiring for the tow hitch is 4 prong flat with 3 extra wires.What was included from the factory and\r\nwhat do I need to pul camper with rv...

With 4 prong and 3 extra, that will give you what you need for 7 prong for towing RV. If your not too experienced in that area, a mechanic at any trailer place, or hitch installation place or who knows RV wiring, should be able to do it for you in about 1/2 hr. or less. Testing the wires from your truck for what they do as in right , left, stop, running/taillights, etc is about the hardest part, and the 7 prong usually comes with what terminal does what.48e2ffb.jpg

I am connecting a trailer towing harness to my Nissan 2004 Titan (2wd), to tow my boat and need to know what the color codes to the parking, stop, and reverse wires are.

if you go to the parts store they make them ready to plug in you will have to just unplug the tail lights and plug the wire harness inplace of it then itll plug back into the original spot.

Were do you hook up the two wires under the hood for trailer brakes on a 2000 silverado

Sometime around 2000, GM started putting trailering pre-wire harnesses in the vehicle. Your truck may have this harness built in and would greatly simplify brake controller installation. Look under the glovebox and see if there is a wire harness tied off. There will be four wires in this harness, which should be run over to the steering column to use it. Most trailer brake controllers are compatible with this harness.
The four wires in the harness are: Red, 12vdc; black, ground; blue or purple, brake pedal; and brown or white, trailer brake wire to seven pin, four pin, or five pin connector at trailer hitch, if your truck came from the factory with a trailer hitch.
If you are adding the hitch and do not have the four wire harness, the under hood wires from your brake controller are Red, connect to one of the studs under the distribution box cover (the distribution box is on the driver's side against the firewall. Underneath the cover are two large threaded studs which are hot from the battery all the time); and the other wire from your brake controller would have to be run the length of the truck along the frame, tied off in several places, to the trailer hitch connector on the bumper. Follow the directions that came with trailer hitch wiring connector to connect this wire to the proper pin in the connector.
If this has helped you, great, and please remember to vote/comment.
Good luck!

I have a 2008 Toyota Highlander with the TO factory option. I installed an aftermarket trailer hitch. Do I just need a trailer light pigtail (to connect to the connector in the rear) or must I also...

I believe the box also is a safety feature in case of a wiring problem from some event, like an accident.
You need a converter to convert the turn signals and brake lights to run off the one bulb on the trailer. A flat 4 pole connector is the usual connection. A 4 to 5 pole converter may also be needed to add the backup light power to disengage the surge brakes while backing up If your trailer has that option. 4 to 5 is not really necessary but it eliminates having to get out and move the connector or insert the brake bypass key.

Towing light problem on wiring them up.

It looks like there could be a service bulletin to fix this.

Toyota will initiate a Special Service Campaign to replace the Toyota Trailer Towing Wire Harness
Converter (converter) on certain 2000 model year Tundra and 1999 - 2000 model year Tacoma
vehicles equipped with a genuine Toyota Trailer Towing Hitch or Bumper Hitch. This accessory
is included in the Towing Hitch Kit installed at ports (PIO) and by dealers (***); it is also sold by
dealers as an over-the-counter or service part.
An electrical short or open circuit can cause a fault in the genuine Toyota Trailer Towing Wire Harness
Converter (converter). This can cause a failure of the converter, and if a trailer is being towed at the time,
non-operation of the trailer lights. In limited cases, the converter housing could become heat-deformed.
In the case of the Tundra, the circuitry utilized in the converter was inadequate to properly manage
vehicle and/or trailer-side voltage spikes. If the converter is exposed to a voltage spike it may cause an
electrical short or open circuit within the converter.
As for the Tacoma, due to deficient waterproofing and improper installation location of the converter,
which is mounted in the lower portion of the taillight cavity of the vehicle, an electrical short circuit will
occur if water enters the converter housing.
The following vital information is provided to inform you and your staff of the campaign notification
schedule and your degree of involvement.
1. Owner Notification Letter Mailing Date
The owner notification will be conducted in two phases:
• The first phase will be launched in late August and involve vehicles equipped with port
installed (PIO) genuine Toyota Towing Hitch Kits.
• The remaining vehicle owners, whose vehicles may be equipped with a dealer installed (***)
genuine Toyota Trailer Towing Wire Harness Converter, will be notified in the second phase
to be launched in early September.
We have attached copies of the owner notification letters for your reference.
If you are contacted by an owner of an involved vehicle, who has not yet received a notification,
please verify eligibility through TDN or TIS, inspect the vehicle to assure it is equipped with the
affected part, and perform repairs as outlined in the attached Technical Instructions.

T connector

Probably feedback through the wiring converter. It converts from seperate brake light/turn signal as used on many late model vehicles to allow a combination light (like used on trailers) to work. Check ground wires also.
