its a low number for a turbo, but it flatlined so I have some issues to work on.

the new sensor works on a different voltage and pin configuration, This only applies if you don't use a pre-made extension! because the extension already has it done to it.
When you extend the wires for the new sensor you need to flip the 2 outside wires for the sensor and then add the 1k 1/4watt resistor across the 2 wires you just flipped.You can get the resistor at any radio shack, they run about $1.29 for a 5 pack.

I had read about it, and knew wires had to be swapped, but I was unaware of the resistor.

Good info! Thanks for the share

**Ill check down my extension for resistors, didnt see any on it at first glance, but ill peel back some loom to check it out

What is the purpose of the resistor?

The Ls9 cam sensor works on a lower voltage range, the resistor is there to drop the voltage so the computer doesn't get false readings.

Does it matter I'm using a ls2 sensor?
