I used to tie to the spring last, spring in place and anchored, do the route with the cord so as to connect to the spring last, feed end of cord through the spring eye, pull cord back on itself until the spring is tensioned correctly, make a mark on the cord with a pen or whatever where the cord is in contact with the spring eye, remove spring, tie cord to spring eye as per the mark that was made (easy to do now as it's not under tension) refit/anchor spring with cord now attached (now under tension)
