I ordered a pair of illuminated sills without the wires/led harness. Is it possible to order the wiring harness for the sills separate?

Can the harness be replicated with by soldering leds to standard wires?

 

I have seen folks add mycolor without a problem using harnesses from other vehicles like an edge, etc. however it isn't plug and play. you need to add a converter (easy to find, but I forget which kind is needed). a simple search will find the answers you need.
