Um, I believe it's a white wires which runs to a grey module behind the AC controls. Sorry I can't be more specific, it's been a while.
I know more details were posted in the past, give a search a try and see what comes up.

Theres no need to connect those wires. It will work just as good with out them. I have the same system. Pioneer Tried to make the 2 new navs. more plug and play, and it works.

The speed pulse generator wire is a back up for when there is no satellite fix (such as in tunnels, or in an 'urban canyon' situation, such as London or New York. If the speed pulse is fitted, the unit has a better idea of where you are, in conjunction with the gyroscope (which checks direction). It is true that the new Pioneer navis have G-force sensors, but I find that they are not very accurate in the Z (can read 0mph in a tunnel when doing 40 etc.); in this situation, the speed pulse generator would ensure one had an accurate postion fix in a tunnel, or very dense urban canon situations.

The Blackwall Tunnel in London is one situation where it is needed; complex routing immediately after the tunnel; no time to get fix, before first turning. Dead reckoning is especially useful in urban canyon situations (New York, London). My Hertz Neverlost got very lost in San Francisco, navigating from the Sheraton to the airport; admittedly, the Pioneer would be better (because of G force sensor and gyroscope), but not as good as with speed pulse generator. if the speed pulse generator is not connected, the pioneer works in 2d navigation mode; if it is connected, it works in 3d 'hybrid' navigation mode; good for climbing mountains, such as in the Swiss alps. Pioneer recommend you attach the speed pulse, and make a big thing out of their 3d hybrid navigation. Having said all that, my speed pulse isn't connected yet, and the unit works fine (apart from occassionally in central London, and at aforementioned exit at Blackwall tunnel).

OK, but for us non-world travelers I would think that the vast majority of people interested in the Nav wouldn't need this.
Also, don't most cities install "repeaters" in and around tall buildings to allow the GPS signal to bounce around them and still be accessable to cars below?
