instrument cluster swap question

[LeesTruk]

For my LS swap into my '80 C10, I'll be using an instrument cluster from a '90 Suburban with the electric speedometer. I've found the pin outs' for the '90 and '80 clusters, so I know what pins to move around and/or reconnect. Do I have to use the temp/oil pressure sensors from the '90 Suburban or can I use the sensors from the '80 C10? The '90 sensors are three pin sensors, whereas the '80 sensors are single blade. Thanks
