VG30DETT VSS imput question

[sweetride2go]

I'm doing a VG30dett swap ('91), but the trans I am using doesn't have electronic speedo pikcup. Do I need a VSS signal for the engine to run properly with the factory ECU?

 

If so, and I install a VSS into the transmission, my next problem is the truck is equipped with a mechanical speedometer. Could I run the VSS signal to an electronic Autometer speedo and then piggyback the signal to the ECU that way?

 

Thanks

Or maybe I could use something like this?

Otherwise I guess I could wire in the Nissan VSS to the ECU and just drive it without a speedo? lol, no......
