Speed pulse wire

I'm installing a in dash GPS this weekend and I need to find the vehicle speed pulse wire location and what color it is. And if anyone knows if you don't hook it up to the GPS how much will it put you off.


THANKS

 

Reverse Light red/white + driver kick, gray 12 pin plug, pin 1

Speed Sense purple/white fuse box, black 13 pin plug, pin 5

There's a post somewhere on here with pictures showing the wires. I can't find it right now, but hope this helps.

 

Hmm curious what it does and why you need to find a Speed pulse wire? What brand Navi unit did you get. The aftermarket wiring harness, like comes with all head units from crutchfield should be all you need to do the install.

 

I have eclipse AVN6620. The speed pulse wire is to help keep track of your location when you loose direct connection to a satelite. Going into a tunnel for instance.

 

wing it stud. it ain't like you're gonna get lost in a tunnel.

 

ahh that makes sense, is that needed because the Navi is not a hard drive navi on the 6620?

 

Thanks everyone for the info. I'm installing a Eclipse AVN5510 with back up camera,blue tooth and I-pod adapter.

 

Yup...

VSS is purple and white wire, behind the glove box.
Reverse is Red/White by driver kick panel.... let me find a link for you....

those were the pictures I was looking for, but I was looking on the wrong forum.

 

haha, yeah don't you hate that.

Also the speed pulse will let the unit sense the speed of the vehilce and estimate arrival time to your destination. It is usually pretty accurate, dunno if it adjusts itself at lights but it's pretty on the money....well in the AVN6620 neways.

Good luck.
