Re: Two ECT Sensors LS1 Where is the other one?
I'm no expert on the newer engines so I did some googling and I read that the ECT comes in a two wire and three wire type. The three wire is for the older engines and the gauge wire ( usually green ) comes off it and is for the temp gauge.
The wire in the back may not be for an ECT but for a cam position sensor which is located on the rear of the block at the cam.
