New user here - Im installing GPS on my 2007 S2000 and the instructions are telling me I need to hook up the GPS to the "VSS (Digital or Analog 0V - 3V)' - - - To the vehicle speed pulse line"

Which wire is this? Most info I have found is on the AP1s and there were changes on the DBW AP2s.

I have the factory service manual, but this doesn't say anything about VSS other then how to trouble shoot it (under the Body Electrical section).


Please help, car torn apart!!!

 

Ok... so I searched the forums again and found this:

It's an install guide for a Modifry Yellowjacket which makes you tap the VSS (blue/white) wire.

I tapped this wire, but for some reason the GPS shows me as going 8MPH even when stopped.

Did I tap the wrong wire? Im using wire to tap it that's a tad bigger gauge - could this be the problem?


So close, yet so far.

Please help!

 

I thought the VSS line, in the cabin, was found under the dash, behind the passenger side pockets? That's were I tapped it for the Modifry DCI speed sensitive volume (mine works).

So I noticed something funny about my GPS Speed Readout... The MPH in the GPS is directly attached to the RPMs. As RPMs go up (when stopped) the MPH in the GPS goes up.

Does the VSS putout an RPM signal on newer DBWs? Any other ideas?

 

Yep, your link shows the speed line I used. There is quite a mess-o-harness back in there. Tons of small wires.

 

it does that on all s2000's, i think

there's a black/white wire in the passenger area of the cabin, i believe it's white w/ a black stripe, try that one (if you need more instructions on finding it, search for "top down while driving")

 

Yep... I hit the black/white wire in the convertible top module and everything is 100%.

Thanks S2Ki!
