Factory 99 dodge trailer plug wiring

I recently bought a travel trailer. but when i hook up the trailer to my truck which has a factory tow package i get running lights and right signal but no brake lights, Lh signal ,back up or brake lights. i brought home a set of temporary towing lights with a four pin adapter and all i get is running lights and thats it!
any suggestions as to where to start?
Thanks
Vance
all of the wiring diagrams i found on line don't match the colors on the back of my plug?

    thanks for the advice i put a multimeter on the truck plug and located all the lights but there appears to be 2 black ground wires because there's 8 wires going into the plug and 7 pins ?

    i now have brake light on the lh side the rh side lights go out. but now i have signal lights on both sides so i'm getting closer.

    do you thing its a bad ground on the rh lamp assembly causing the lamps to go out when the brakes are applied?

    i really appreciate the advice. thanks

You'll need to disconnect the wires from either the truck connector or the trailer connector...
I highly suggest purchasing a voltage checker- it looks like a screwdriver with a pigtail of wire with an alligator clip on the end. The tip of the 'screwdriver' has a point for probing. The light in the probe will light up...makes it easy to trouble shoot without a helper behind the trailer.
Hook the aligator clip to a good positive grounding point on the bumper or frame(not painted).
then pin by pin on the truck connection, stick the probe on each terminal tab.. and write a simple diagram where you find brake, tail, backup, etc...
Then i'd suggest, taking the connector off of your trailer, exposing the wire ends.
Run again thru your diagram and turn on each light of the truck. As you do, touch the wires from the trailer to that specific terminal. (make sure your ground wire is attached on the trailer) you can mark each wire with a piece of tape and label it which is which.
then simply attach your trailer wires according to your diagram to the terminals in the connector... that should get you in business..
hope that makes sense...
That way if the factory wiring harness remains the same, you'll be able to use it with other trailers if the need arises..

The trailer plug wiring just taps into the truck harness to the rear lights so if the truck lights work, the problem is in the wiring, not a fuse.

Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.

2006 dodge ram 3500 no left turn signal or left brake coming out of the tow package......no power back there for those lights. any solutions before duck tape and toggle switches are implemented???? LOL


There will be a connector where the tow package wiring hooks up into the main wiring harness. Trace the wires from the trailer plug back till you find the connection place. Wiggle or carefully remove outer protection.
You will find the bad connection if you are patient.
It is to nice of a rig for duct tape and toggle switches.

2003 Dodge Ram 3500 left turn signal problems / trailer


Well let me shed some light on this issue. I have the same problem. Trailer connection from truck does not have power to left turn signal and left brake light. I just got back from the dealership and $100.00 labor charge. My problem is the TIPM (Fuse Box for short) and FCM (little silver module hooked to the Fuse Box on the left hand side of the fuse box). $910.00 for the parts and Chrysler doesn't have any in stock. 4-6 weeks to maybe fill a back order. I am currently researching an alternative way to fix this issue. I will let you know.

I do not have power on the aux. terminal in the trailer plug on a 2008 dodge ram. Any ideas?


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.

Trailer hitch...no running lights (2004)


You'll have to follow the BROWN wire from the factory connector(with the running lights on of course) to the trailer connector and make sure you are getting power all the way to the two lamp fixtures. If so you've probably got two burned out 1157 bulbs or an inline fuse in the factory harness/ trailer harness.Good Luck, Dana

Need wirering diagram to hook up trailer lights and elecric break


Also try http://www.etrailer.com/faq-wiring.aspx. They have a great website with lots of info. With the tow package, there should be a plug under the dash... far left above the emerg. brake petal. The harness that plugs into it should have came with the truck, or you can order one to fit it. Did thew truck come with a 7 pin plug on the back? If not you can order one from the above mentioned site. They also have the wiring colors.

2001 Dodge Dakota Trailer Brake Wiring


Call dealer & ask them to run your vin# to see if it came with towing package. They shouldn't mind. If not, you'll have to wire it in yourself.
