Anyone with experience on 3.0L might be able to help. I am putting in the crate 3.0L from Jasper with the help of 2-3 others. We all work at seperate times, so there are times when we fumble over each other. The question I have is this. We are moving the old top end onto the new engine, and my friend noticed a broken bracket on a sensor. The sensor is on the back (flywheel), and (facing the front) on the left (passenger) side. It is screwed in to a larger piece that sits behind the fuel rail, and IIRC this piece also connects to the heater core. Any idea what this sensor is? I have to replace it, so it'd help to know what I need...and if it's an order item, if it will hold up finishing the install, or if I can replace it after the engine is up and running.

Thanks!!
