I installed mine (Edge part # 98600) in the drivers side manifold, gave it a decent bend radius (6") off the probe into a factory bundle, routed it through the existing firewall holes left of the brake pedal, routed and tied it under the dash, and had about a foot to spare.
Best thing is to not drill the manifold, but just hang the probe next to it (leaving a few inches for slack) and just route it in to see if it makes it.
If you don't mind my asking... Why not just install it in the drivers-side manifold like everyone else?
