vss wire location for 07 honda element

Hello,

I was hoping to find the location of the VSS wire on an 07 Honda Element EX.  This is for an install of a Pioneer D3 to get the speed pulse working.

Any advice would be appreciated. 

Thanks,

Thanks for the yahoo link.

I have checked the relevent posts and found that people are recommending a blue wire on a gray connector (A pin 18) but everyone is getting errors when hooking up a nav system to it.  Crutchfield.com is saying:

So I was hoping to get a difinitive answer from the experts here to do this nav install propperly.

Thanks,
