I just found a s5 n/a engine streetported for my car but it doesnt come with a wiring harness. I have a s5 n/a so everything is the same but my engine isnt streetported. I know its easier to pull the engine with the harness but would it still be in my case, since i need it back in on the other engine?

My car corrently hase no power steering, ac, cruise control, fan/rad removed, exhuast off, driveshafts off, battery off, and all front panels. So by the looks of it its little work to do the engine swap. But how about the harness how long will that take me to do?
