If you have amber signal lights & red brake lights, it's 2 separate circuits. You'll need to buy a small converter that you wire into harness to correct that. Not expensive, try autoparts store or RV/trailer sales, should have them.

SOURCE: factory 99 dodge trailer plug wiring

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..

I Have an 2005 chevy duramax. i purchased and S&H horse Trailer. When i plug a five prong round into the seven pin with an adapter the horse trailer on the passenger side wheel locks and drags


I would start by making sure the emergency break away switch has the plunger in it and it's working properly. If everything is OK with that then the 5 pin plug must be wired incorrectly. If you only tow the trailer with that truck I would suggest changing to a seven pin connector on the trailer. It would appear you also have a problem with the left trailer brake. They should work together.

I have a 1997 Ford F150 4x4 Supercab Stepside with 5.4L and factory towing package. On the factory trailer wiring plug I am not getting power for turn signals or brake lights. Running lights and brake...


It is a possible option that the relays for the Stop / Turn are having an issue or the fuse in the Engine Mini panel is blown ( page 142 of the 1997 owners manual )

On the 1997/98 MY this is in the aux relay box in between the Engine Compartment fuse panel and the engine mini fuse panel.
9349aa0.jpg

The output of the MFS ( Multifunction switch ) triggers the relays, to use the trailer tow fuse to operate the trailer lamps. The fuse to supply power to the Normally Open contacts on the trailer relays should be hot at all times. You can verify this with the diagram below by metering from pin #3 to pin # 2 [ground for coil] or to another known ground.

These are 1/2 size Ford ISO relays, and can be jumpered to make testing easier ( and with this diagram you can bench test them with a meter to check resistance over the Normally Open contacts, when applying power and ground to the coil ).

I am not 100% sure on the 97/98 MY F-150 about the location of this connector, but the 99-03 have all the wires to the rear of the truck via a connector along the driver's side frame rail, that you can check for ( easiest with the spare lowered )
777e616.jpg

Start with the Fuse in the Engine Mini panel, to see if the 20A fuse is good and work back towards the trailer tow adapter via the relays. I am going with the obvious blown fuse for the Stop/Turn lamps for the trailer.

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.

04 DODGE RAM TRAILER BRAKE WIRING


If you have a seven pin connector in your tow package, you should be wired for electric brakes. just need the brake box.usually in your owners manual it will show you where to plug the box into. the best thing to do is contact your local chrysler dealer and ask them.if you give them your VIN number they should be able to tell you for sure.

Installing a 7-pin trailer towing recptical on a 1991 Ford F150.


I believe you can look up the manufacturer of the trailer plug kit and find the wiring diagram there. On alot of the trailer plug kits, they have pics and diagrams in the package. The 7 pin plug (truck side) is available with the pig tail set up that plugs directly into the wiring harness for the lights. Then all you would have to worry about is the 2 wires for the electric brakes.

Can you tell me if the 2005 Colorado came with electric brake wiring with the towing/trailer package?


Any trailer tow package vehicle should have at least the light wires.On a truck of that size it probably didn't come with a seven pin plug but it should have a four pin for lights. Hope this helps...Dan
