LED to NON LED Taillight Swap.

[2003 SSEi]

I know this is not the typical situation but, I have a local guy that has a 2017 All Terrain SLT with the OEM LED Tails.  He likes the look of NON LED Tails better and would like swap with my 2014 Denali Stock Tails.  I know GM changed module connectors between the 14-15 and 16+ trucks and the taillight harness is different.   I also know I need the Phil G harness or a Gen5DIY to swap into MY truck, but how do I go backwards to make HIS work properly.  

 

I recently read someone tried to swap a Silverado from the OEM LTZ LED to the Morimoto LED and was having bulb out warnings on the dash and hyper flash.  I want to avoid that as I don't want to give the guy im swapping with problems, as he is not mechanically inclined.

That other guy had problems because moromoto resistors are built into the tail light. He won't have problems other than the plug tail being different

The bulb out warning is only due to the computer looking at the draw of the led being less then the non led. Going from led to regular lights won't cause that issue.

And as always... Enjoy your ride!

Are you positive? I’m thinking each type has a certain load range it’s looking for and anything out of that load range will cause hyperflash.

The BCM is programmed to read the led tail lights, not from a resistor.
