I used 3/4" black flexible conduit and DG12 adel clamps to protect my EMS sensor wire runs across the top of the engine mount. I used my super-sharp hose snips to carefully snip a split down the length of the 32" conduit, allowing me to part the conduit open and "swallow up" the wires. This wiring protection is similar to the solution I've seen in new Cessna 172s. I'll add a few more zip ties down the lengths of the conduit just to keep all the wiring tucked in.
