Q: Just had replacement wing wirrors with LED's in them but no instrutions on how to fit
A: The assembly should come as a total replacement for the faulty or damaged mirror. There is a single connector for the LED turn signal indicator and the assembly is secured by reversing the removal process and making sure the two clips are compressed by the set screws so they do not loosen over time. You will need to reset your display after testing the turn signal to erase the warning regarding the indicator light, usually something like 'R F Reflector.' Good luck.
