You can put it through the steering grommet. I have my boost gauge line running through there.

Take off your driver wheel, and remove the fender liner - 10mm bolts under there, easy.

Front and back you'll see giant grommets, alternatively there's a grommet for alarm horn & relay on inside back but I'd go front/back.

The sensor will come up near the radiator & overflow underhood, and route under fender through front grommet by ABS. Ziptie up to existing wiring under fender, go through firewall grommet, and you'll have enough wiring through to solder extensions from the driver side floor area.

I ran 3 extension wires from ECU - analog, power (off MPI with inline fuse) and a fat ground ring terminal off ECU chassy ground. Solder all eleventy billion ground wires to that big ground wire if you're good with an iron. Otherwise get a terminal block and screw each ground to a unique terminal.
