I'm doing a turbo timer install on my 2005 Infiniti G35 Coupe. I've found most of the information I need, but what I can't find is the pin out, wire description for the speed sensor wire. RPM signal wire comes out of pin 62, but I can't find the speed sensor signal wire. From everything I've found, wiring diagrams will be the same for all 2003-2005 Infiniti G35 Sedan/Coupe and the Nissan 350Z.

You can find it in a lot of places, the easiest is the AC display in the middle of the dash. I believe it's a WHITE/ green wire there. It is also at the radio and at the sunroof controller (not sure why).

Is that running to the Unified Meter Control Unit in the dash? Or is it the actual speed sensor wire. Everything I've looked at runs power to the Uified Meter Control, and shows the tach and speedo as attached in parrallel, but nothing on the actual speed sensor wire.

The actual speed sense wire is at the combination meter (cluster) pin 14. It is a WHITE/ green.

It's also pin 17 (WHITE/ green again) at the Display and A/C Auto Amp. The cluster is a pain to take out, the Display and A/C Auto Amp is simple to take out.

It's on page 47 of the ATC.pdf file in service manual marked as Speed Sene

Sorry about the delay. Trying to get the rest of my build done too. Thanks for the info. It's been a big help.
