Speed Sensor for Nav.

[Msugi07]

Hey guys,

So i'm installing a Pioneer AVIC-X940BT and it has a wire/cable for a speed sensor. I'm assuming I need this for the nav. On the OE harness, there are two data link connectors for CAN bus transfer. One is high, the other low. There is only one wire/cable on the new deck for a hook-up. Any ideas on how this can be done or if i'm even looking in the right place?

Ok guys. So after hooking up both wires (separately) and driving around for while, I've found that those are not the speed pulse wires. Yes they are hooked up to the CAN bus, but didn't provide me with any infomation. Anyone else have any other ideas on we're to locate the VSS (vehicle speed sensor)?

So I found the VSS. It was located behind the gauges under the dash. Fairly easy to get to. The harness is white, and you feed a striped wire threw the upper row (near the clip), fifth pin from the left.
