My name is steve i have a 02 ram 1500 4.7 lv 8... Just bought the truck and dont know what is with the signals and rear daytime lights... put a signal on and it will work press the brake and it blinks fast in the front and cuts out in the back the brake light takes over. no rear driving lights for nighttime driving. there is a switch in the cabs dash that looks to be wired from the batt to the swich than the swich to the ground than the swich to the rear tail lights.. When the swich is down stuff kinda works but not the way it should. when it is up i have no power to the rear.. the factory trailer plug wires are cut and not connected to anything insteed there is a 5 pin wired into a crap load of wires under the truck... i have checked all fuzes and relays and cant find the prob.. any ideas ?? thanx
Sounds like the previous owner patched a hot wire to the rear lights instead of fixing the problem.
Someone will need to get the factory wiring diagrams and start backtracking from the lights to the dash to find out what is wrong. You may need a shop manual to get the diagrams you will need. Most repair books do not go into wiring that deep for the DIY.

I'd get a 12vdc test light if you don't have one already & start from plug, and keep probing back from there. It may be as simple as a bad connection under truck where joined into harness.

It should have a fuse for the marker lights. Do they work on the truck. Brown is the color for the marker lights. Good Luck

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 seen once before that the fuse box was bad on a 2003 Dodge 3500. I had power in and nothing out. We had to replace the box. Not cheap! Hope it is simple like a loose connection though. I think I had to pull the inner fender on the drivers side to access the bottom of the fuse box. Pain in the ****, but...

Check with http://www.etrailer.com/faq-wiring.aspx. Sounds like a faulty converter.
