Saxo Speed Pulse Info Here
Hi
After searching hi and low for the correct location and correct colour wire for the speed pulse, and getting very differant answers, ive found it.
I have various websites and data bases at work, which we use to find info on differant vehicles, but none of them seemed to be correct or give the correct colour wire. I did not fancy removing the clocks, or probing endless wires.
You would use the speed pulse wire to connect to a sat nav, or anti hi-jack feature on an alarm. Most navi units dont need speed pulse to work, but its nice to connect up if you can be bothered, or want to give it more accuraccy.
The easiest location to pick up your speed pulse wire is from the speed sensor off the gear box, which is feed off the drivers side drive shaft, this is the one suppling your speedo in the car.
You access this by removing the airbox and pipe work from the engine bay, if you have a cone filter this will be alot easier, you can then see the connection just were the lower part of the air box sits.
The plug you are looking for is White, with 3 wires in it, it has plastic tubing running upto the main loom.
The wire colours are:-
Yellow and Green- Earth
Red- Live
Green- Speed Pulse
Green is the one you want, strip the insulation off, wrap your wire around it and solder, make sure you insulate the wire after.
You can run the wire through the grommet your power cable is going through, which is just above.
My car is a 2003 VTR, I would pressume the wiring to the speed sensor is the same on all ages and engine sizes, but check your colours first.
Hope this helps someone.

Basicly, it gives a signal to a navigation system or speedo to tell it your actual speed of the road wheels, instead of just using a GPS signal.

Not quite sure what you need mate.
The speed pulse is an analoge signal to be wired to speedo, clocks, gps, units, etc, voltage will be very low.
In the plug the is a 12v supply, but cannot understand what you would use it for? I wouldnt run anything else off the 12v in that plug, just the speed pulse.
