I put my wires through a hole right near where the throttle cable goes through

I've run quite a few wires through that hole (tach, poer wire for amp, wire for elec fan)

If you are looking at it form the engine compartment it should be about 6-10 inches below the wiper motor. It is there, sometimes you just have to find it
