Re: Two ECT Sensors LS1 Where is the other one?

Theres not two ECT sensors on any gen III engine the PCM sends the temp signal through a serial data line to the insterment cluster in a stock app.

The wire you found in the vette harness is probably the oil temp sender plug no other apps had this exept the vette.
