So I was changing my bulbs and noticed that the previous owner had a hid kit I stalled, do I simply removed the hid harness and figure out the stock wiring route ? My low beams work but high beams arent

 

So, the previous owner installed HIDs and you didn't notice? Weird, since they're way brighter than stock. As far as removing them all you have to do is, well, remove them! There shouldn't be any wiring harnesses that you should have to follow for the stock bulbs. The HIDs should have a harness leading from the positive terminal of the battery to eventually the left side headlight connector. There should also be a ground wire somewhere on that harness too.
