Unplug the lights at the sockets inside the switch housings. Cut the connectors off the lights leaving about an inch of wire (in case you want to put it back to standard later - alternativley just buy some new attractive lights). Open the headlight bucket and locate the turn signal wires running through the bucket, then use "scotchlock" connectors to splice into the wires, using some new lengths of appropriate gauge wire to run the lights to where you want them. That leaves the bike as standard as possible so you can put it back to original simply by soldering the original connectors back onto the lights and plugging them back in. This also means that you can use the original wire to connect some bar-end turn signals at a later date if you like.
