rear light upfitting help please

[naysmith76]

We have a 2019 Ram Chassis cab we upfitted with the bed from another truck. It has duel stop/turn lights on the back. They are incandescent bulbs. We had it to a local dealer because the rear lights were acting funny as soon as we hooked everything up. The dealer thinks the two lights per side are drawing too much power, so they disconnected one on each side and now works fine. How do I connect them so I can run all four.?
Here is a pic of a similar light set up (only ours are not LED).
Thanks for any help.

If you change them out for LED lights, the power draw should be lower and that may fix the issue. LED bulbs in the existing housings may work as well, as long as they are canbus compatible.

From the picture they look like LED but I have been wrong before. I have been told I am wrong already today by the other half and the day has just started!

There must be an issue with the wiring in the bed because you will have more lights when you connect to 7 pin connector

The 7 pin isn’t connected to the taillights, it has its own circuits.

I’m pretty sure I read somewhere on chassicab models there is an option to disable the canbus feature for rear lights only so people won’t have problems with whatever lighting they add. See link Disabling light out condition

Here is a video I ran across a while back. I know it may be for an earlier model but it might still work on 2019 and 2020 models if they are wired similar.
