I don't fully understand what you mean (especially the "yellow" and vector part), but if you just want to draw the line behind the arrow, you can do it with css animation and the properties stroke-dasharray and stroke-dashoffset.

You just need to know/guess the correct path length and keep the duration of the (arrow and path) animation the same.
