I quite recently bought a Blaupunkt Stereo/Sat Nav unit for my R34 Vspec. Despite several attempts NOBODY so far has been able to give the exact location of where I can get a "Speed Pulse" output and thus the unit is always a few hundred yards out in it`s location. Will be confusing away from my home area.
Does anybody know for certain which wire is the correct one??
Thanks in advance.

Speed pulse?

According to the wiring diagram of the ECU, the speed signal is given by the following wire output.

ECU when looked at should have the following plug arrangement,
16 pin plug, 20 pin plug, 20 pin plug, 20 pin plug.

The engine rpm signal is given as pin 7 top - first 20 pin plug.
Vehicle Speed Signal is given as pin 3 bottom - third 20 pin plug.
Power is given as pin 8 bottom - third 20 pin plug.
Ignition power is given as pin 9 bottom - third 20 pin plug.
Ground is given as pin 10 bottom - third 20 pin plug.

This is for the Apexi mod drawing where the ecu is quoted as type N1 (R32/R33/R34 GTR ecu)

Hope this makes sense?
And is what you are after,
Matt.

Vehicle speed signal is given as pin 3 bottom - third 20 pin plug.

Wire colour?

Couldn't remember off top of my head, the cars in bed and I have to catch a flight offshore at 6am so didn't want to check.
Needless to say, you are probably correct!;)

Cheers,
Matt.
