3rd Gen Trailer Left and Right Turn signals/brake lights not working

The "module" is an integrated part/section on the combination meter pcb. So unless you're an electronics expert and have the pcb blueprints the DIY would be NO.
You have a few choices though:

• New Combination Panel with milage sticker.
• Aftermarket Towing Module using the rear lamps inputs (Left, Right & Stop) and de-pinning the towing connector to add the output of the added towing module.
• Same as above, but with 4 or 5 pin solution pigtail end hanging at rear bumper.
• Adding the 2nd Gen Towing Converter, but needing to cut the OEM wiring.

 

What after market lights do you have. I'm having the same issue and I have neso stage one kit. Im wondeting if that is causing a problem
