LS1 swap to LT1 coolant Temp sensor wire?

Just wondering how does the LS1 send the coolant temp signal to the cluster? I just did a swap with a friend ls1 into lt1 95 Camaro and I can't figure out how the LS1 sends coolant temp signal to cluster, does it use pcm serial signal to feed temp
? I know there is a yellow wire on blue connector at pcm that says "pcm signal out" but where does it come into the inside of the car? Don't think the LS1 c220/c230 connectors have it anywhere there?
Thanks.
I'd rather not install lt1 temp sensor and feed inside rather use the stock ls1 sensor.

What year is the LS1 that you swapped in? The 98`s have a 3 wire sensor that hooks to both the computer and the cluster. The 99+`s use a serial data signal from the sensor to the computer and then the PCM sends the temp to the cluster as a serial data signal.
