I have a set of power folding mirrors that i picked up and the question came up in my head about adding the bliss option without having to add the tail lights?

I have already added the door modules and harnesses from the highest package truck so I know that stuff will work.

 

If you are asking if you will have BLIS functionality without the tail lamps, no.

If you are asking if the other features that you have the wiring and modules for will work on a set of BLIS mirrors, yes.
