So I am wiring my amp up and I am just curious on where the grommet is on a 05 f150 to run the power wire from the cab to the engine compartment. If anyone knows please help!

Worf

I know when i ran the power wire for my alarm i pushed it through the rubber that covered the steering colum down on the floor.

There's a circular rubber grommet to the upper right of the gas pedal; the gas pedal's "drive by wire" passes through this grommet into the engine compartment. I've used this grommet to pass the wire needed for my indash Pioneer GPS systems "speed sensor" wire (connected to the sensor on the side of the transmission).

That should work for you.

Out of curiosity.. why does your GPS need a connection to your truck's speed sensor. Shouldn't it be calculating speed on it's own?

This!?!?!

Uh.. what are you trying to say?

CrashTECH

I want to know too? lol

Basically saying what you said without saying it

Ah.. gotcha.

I am guessing it's so the GPS can still guestimate your position if you hit an area of low or intermittent signal.. that's the only reason I can think of.

That would make sense... although most newer GPS units estimate based on the last registered speed. The TomTom unit I have does that.
