? on an LT1 swap

On an LT1 the temp wires coming from the computer are available, but not hooked up. I was told they are active wires. For me to use the wires would I just need an electric gauge to tie into the wires? (ones engine temp and other is oil pressure) Any knowledge is appreciated.

The PCM doesnt control the oil/coolant wires on any GM engine

Run them direct from your old C100 wiring with the newer connectors to fit the LT1 sensors
