Speed Pulse (speedo) Wire

[Lee]

Does anyone know the location of this wire and what the colour of it is???

I needed to find the speed pulse line in my S70 for my sat nav. There is a speed pulse line into the stereo (so the stereo volume adjusts as your speed adjusts). IIRC it is black and yellow. I assume it's the same for an 850.

Hope that helps.

Depends on what year your car is mate

I`m sure that most of the S/V/C range don`t have a speed pulse line as the speedo reading is taken from the abs sensors on the front wheels and interpreted via the ECU into the reading on the speedo

using the book of lies isn't helping.

It does how ever state that there is a pulse sensor but can i find it in the wiring diagrams can i chuff.

Hopefully the V70 is the same as the 850 and the yellow/black wire is there. I will go and check.
