Question about Nissan Titan

2 Answers

The trailer brakes on my 2004 Nissan Titan do not work. Where is the sub harness located?

I hooked up to a travel trailer and noticed a spark when plugging in the 7 way receptacle. After checking all fuses in the fuse panel, the trailer brakes still do not work. Last time I had a problem with the trailer lights it was in the sub harness fuse. Where is the sub harness located?

You will need to get a 12 volt test light and check the trailer connector for a voltage signal to the trailer, it may also have seperate fuses under the hood for the trailer lights if the system is factory installed, federal law requires the 2 systems be isolated, if there are blown fuses find the short in the trailer before replacing fuse(s), with no exceptions the short is always in the trailer. Hint, check the fuses 1st.

Depending on what type of trailer you have, a blown lightbulb on one marker could kill them all (like the old Christmas light strings). Look at those, and make sure your ground is good.

There should be a fusible link somewhere in the wiring. That should be where the problem is at.

Should be in the front under the hood in the main fuse box on the left side of vehicle . look for the aux fuses for the traler plug.

Hello gary823

Thank you for choosing fixya.com.

First things first: I suggest taking your truck to a mechanic or an auto parts store that can do a diagnostics test done. If any fuses or relays are blown, this test should bring up any codes that would indicate any type of malfunctions.

The shift lever being locked: In newer vechicles, the brake pedel, as you know must be pressed in order for the transmission to be put into gear. There should be a sensor on the transmission that runs in cahoots with the brakes. This sensor tells the computer what gear the transmission is in. It is very possible that at the last time you put the vehicle in Park, that the switch had it's final moment of ability. If the sensor is in fact useless, it may be the reason the transmission is locked into Park. It may be the reason why the brake lights aren't working; and why the brake lights fuse is blowing. Also, check all relays, (can be tested with a fuse tester) and make sure all relays are good as well. Make sure also that the light sockets for the brake lights, tail lights, back up lights, and front running and blinker lights are in good condition. One faulty socket, can cause more than one bulb to blow, or cause fuses and relays to blow as well. Follow the wiring for the brake lights for as far as you can to ensure there is no damage (melted, broken, etc.). This could also affect fuses. This truck I see is barely 5 years old, but you'd be surprised how quickly parts and wiring and such will go bad, or wear out and/or just quit working.

If the transmission sensor is not the problem, and all fuses and relays are good. tranny fluid is full, check the linkage under the truck. It may be jammed somehow, or stuck. On the transmission, where the lever inserts, there is a seal - inside that seal, there is like a gear that the lever pushes in order to shift from gear to gear etc. You may need to have that checked out to make sure it's not broken inside. If your fluid is low, or empty, you may have froze up your transmission, however, you most likely would have been seeing large amounts of fluid in the frequent places you park. Another think to check is your differentials. Make sure the fluid is full in each, as well as the seals not leaking. The seal sits just inside the inner most part of the pumpkin (differential ball) where the yoke is inserted. Maybe you have just locked up the rear driveline. Check the seal on the front end of the driveline as well, (goes into the rear of the transmission (yoke). Check your U-Joints as well, making sure they are intact, tight. It may be a good idea to have them replaced if they look supsicous in any way.

These are all the things I can think of that would make your truck be stuck in park, and make your lights not work, and blow fuses.

I sincerely hope this information is useful and aides in the successful repair of your truck. Thank you again for choosing fixya.com. Please let me know if I can be of further assistance, or if you have any more questions or concerns (comments).

Thank you again,

All trailer lights work on my travel trailer except there are no brake lights to trailer. The issue I can see is there is no power to the brakes at the 3:00 o'clock and 9:00 o'clock pins on my 2004 g


there will be only 1 power wire for the brake lights as they are connected .together. What you are looking at are the indicator lights (1 left wire and 1 right wire)

If the blinker is working on the truck then fuse is good, this sounds like a bad bulb or connection to the light, the brake and signal use the same filement in the bulb. check the bulb first, next thing to determine if its the trailer wiring or the truck socket, use a testlight and test the connector or the wire at the trailer connector and see if there power in the wire, but check close to connector if theres power coming out the connector then it in the trailer wiring or bulb,. also im not sure what this trailer turn relay rh is that you speak off. the only thing i could think of is to converter the signal and brake on the truck to operate the same bulb on the trailer, if this is what you installed then check that wiring also as the controls the lights to the trailer, but if this truck was built with the tow package then it should of be wiring already for this. here a good site to help you with the wiring as this gets hard to explain over the computer, but again test the tow connector on the truck first with a testlight, this way you will be able to see if it the trailer wiring or the truck wiring to connector. google trailerlightwiring. good day. let me know if you have any other questions.

OK on the truck side, brake controller harness wire colors are:

RED = +12V (Hot at all times, even with truck off)
RED/GREEN = Stop light (Hot when brake pedal is depressed)
BLACK = Ground
BROWN/WHITE = Brake out (variable voltage to trailer brakes, 2v-12v)
RED/BLUE = Dimmer (not used on most controllers)

On the controller side (these are pretty much universal):

BLACK = +12v
RED = Stop light
WHITE = Ground
BLUE = Brake out

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.

Yes you need the tow relays. U-Haul sells the set of three for around $25. Dealers sell them for a lot more. Do a web search for 'Titan tow relays' for more information.

sounds to me like the fault lies between the trailer plug on YOUR truck ( not the work truck ) and the L/R brake and signal light assy on YOUR truck. Just follow the harness from the plug. You'll find the problem. Hope this helps
