You can remove the A pillar cover to lay the wire up to the roof and hide the balance wire using the gap just on top of your wind screen. Stand on the outside of your car, both palm on the A pillar cover and push inward toward your steering wheel.. it should come right off. But pls note do not do that if you have air bag on in the A pillow.
Typically, I insert a long screwdriver from the top of the A pillar, then pry it open from there, best to apply pressure where to clip is. I've opened up C pillar with air bag, just remember to wire away or behind the air bag and not have your car powered on while doing so.
For TS, there is some steps to go through to totally hide the cables.
First is to route the cable inside headliner, down A-pillar then through the dash. For this, you might have to remove some of the panels to see the inside of your dash for easier routing.
Then, you will need to hardwire the cables to the car's power supply. I typically like to buy a cigarette lighter jack, connect the wires behind this jack to existing power source, then plug the accessory in and hide the entire set up away inside the dash.
