About a year ago I was looking for the location of the vehicle speed signal to connect the speed cable from my HU. Well, I searched on the forums found this.

Today I needed somewhere to feed this sneaky speed signal to my EVC 6 so I can program boost per speed... and... I found it! It's on the combination meter. The signal comes from the ABS sensor and talks via CAN to the speedo. Refer to FSM Section MWI page 60 and 61.
I removed the gauge cluster following this instructions by Digi
DIY: Interior LED Color Change and found the 2 connectors shown above right underneath the cluster.
Take a look at the 24 pin connector where pin 4 should be..
There is nothing on pin 4. But look at the FSM again and the (L) blue cable on pin 3 is also a speed signal. It's a 2 pulse instead of 8 but it works... and there you go, tap into that and you now have a speed signal source.
If anybody knows of an 8 pulse speed signal source on a nismo (base) please disregard all this, and share!
