Need help with speedometer and pin 50 in ecu I have a cable x box for my speedometer on my chevelle and was wondering if pin 50 is the correct pin to get a speedometer signal out of. this is a 2007 lq4 6.0 truck engine. Other wise I will just tap into the speed sensor wiring. I just left pin 50 as my speedo wire but it may just be a communication wire to the cluster. I cant find any info on this at all. I also need a tach wire to hook to, anyone know which pin to get that out of.

With a cable x box you have to tap into the sensor wire to make it work. I called the company when i installed mine and they said thats the correct way to wire it and mine works perfect.
