Throttle Cable Question

[Leon.stt]

Guys,

I just finished M52B28 swapping my sedan.
One thing really bugs me is the throttle cable position. I custom made the cables, adapted to the M52 throttle body and the gas pedal. But as you can see from the picture, the cable is on top of the engine. I did try rerouting it through the back of the engine near the firewall, but the throttle became very heavy and I'm worried it could get stuck. Any suggestion what I should do to make the engine bay a little neater without having to sacrifice drivability?

Oh forgot to mention, my car is right hand drive. So the cable has to cross over from the throttle body on the left hand side to the gas pedal On the right
