Wiring diagram needed for running and tail lights?

Here are the tail light wiring diagrams you have requested, I have seen the TIPM go out and cause tail light issues, also here is a guide to help as well.

Hello,

I have included the information that you have requested in the diagrams down below. Please get back to us with how everything turns out. I hope that these wiring diagrams help out.

Thanks,

I enlarged these as much as I could. If you can't read them, I can cut them in half, then make both parts bigger.

Be aware the rear tail lights are on two different circuits, and they're fed from the Totally Integrated Power Module. That replaces the common sense switch with a computer module. As such, there are two things to keep in mind. The first is you don't want to overload the circuit and risk shorting a driver transistor. If that looks like it's going to be a concern, check if you have relays in it for "Trailer Tow". Those relays can handle plenty of current and won't affect the other lights. If you switch to LED tail lights, but now you have more than were on the old box, all together they might draw enough current to prevent getting a "burned-out" bulb message. If you don't have a Trailer Tow relay, I can help you add one if needed.

The second thing is you're going to want to separate the tail lights into two circuits, one for each side. I don't know how forgiving the system is as far as detecting burned-out lights, but if, for example, you only use the left rear tail light circuit to run all the tail lights, that will leave you with warning messages about burned-out right tail lights.

I am sending the blinker wiring diagrams and for a back up lights are violet color wire and there is one that is pink/violet.

This guide can help you test

Check out the diagrams (Below). Please let us know what you find.

These are for a Ram 3500 5.7L 4wd. There's way too many to link together, and each one of these takes a full page in the paper service manual. If you need to enlarge them, I copy and paste them into an MS Word typing program, then you can click on the different sizes to make them really huge. That's how I format them here to make them as big as possible, then I copy them into MS Paint to save them in a format that can be uploaded.

Let me know if this helps, or if you can't find something. Sometimes it takes a while to find what you need.

Hello,

If I can jump in here. the TIPM goes out on these trucks. To be sure here is a wiring diagram so you can see how the system works and a guide to help you confirm the failure using a test light with the instruction on how to change out the TIPM. it is easy because it self initializes.

Check the power outputs at the TIPM and fuses. Check out the diagrams (below). Please let us know what happens.

I included two different diagrams. The first is the portion of just the tail lights. This is good but there are times that I found I need to see how the other lighting components relate. This is why I included the entire exterior lighting diagram. This can get difficult to follow at times but it is all there.

Let me know if you have questions. Thanks

Does that bed plug into the trailer harness wiring like it shows in the first image? If so that is likely the reason the monitors are coming on. They are looking for the loads from the original bulbs and finding nothing because the trailer circuits are not monitored, only the original bed lamps. If you wired them into the original wiring harness where the OEM bed plugged in the disregard this.

Good morning,

So you're thinking that the trailer wiring is not stock but after market? I would try to get to the stock wiring for the brake system and if you can remove from the circuit anything trailer and get it to function properly with just the truck wires. Here are wiring diagrams with wire colors to help you get into that harness:

You might have a bulb that is working but triggers the warning check out this video.

Make sure you check all the bulbs front and back for open filament In the power distribution box check fuses-no.4/5/F 20amp fuse. if there okay The wire you're looking for- the turn signal circuit is the dark green and brown on the back Also test out the combination flasher in the junction block and the turn signal/hazard combination switch.

Please let us know what you find. We are interested to see what it is.
