Speed pulse. I know this has been covered but..

[rob192]

I've done various searches and gone through pages and pages of questions about this but I still can't find anything conclusive.

My car doesn't have a speed pulse wire on the ISO block, so where am I likely to find it?

I've got a 98 Mk2 Ph1 RN which has a rev counter (I hear some don't).

Cheers,

Rob.

I don't know much about your car, but has it got ABS? it may have mechanical speedo rather than electronic.

Hi mate the wire you are looking for is behind the instrument cluster in a 30 way plug the pin number is 23. that will give you the speed pulse for sat nav units etc

Its used for the head unit to adjust the volume (if its acticvated etc) on the stereo ie the car goes faster the stereo get loader.

On the back of the dabboard there a few connectors the black wire on the black connector block is the speedo signal.

Thanks for the replies guys.

Take it you both mean the same thing? Is there any way to get to it without taking the dashtop off ie at the fusebox? And one last question, am I alright to just scotchlock a wire onto it (being the hardcore auto electrician that I am)?
