Got it...

I googled, and found this page which shows how to add an inline resistor to convert a 3-wire harness to use with a 2-wire sensor. I didn't read it in detail, but I imagine something like this is what you need, so it might be a place to start:

https://www.autosportlabs.net/RaceCapturePro_Sensors

This is creating a voltage divider, allowing the ECU to read the varying voltage at the analog input. The sensor itself is a variable resistor I believe.

Also check out the first post in this thread, which says the 98 LS1 had a 3-pin CTS sensor. Not sure if you could use that?

Maybe some of this will help...

Bryan,
You are spot on with both options. I was told by an EFI tuning expert about the resistor work around. Also found the 90-96 Corvette uses the 3 wire sender. I have ordered one of those.

You are WAY better at 'net searches than I am. I had looked for hours, and didn't come up with the info you did.

Thanks for your help! I appreciate it.

Bill

Glad I could help... I googled "3-wire oil temp sensor" and started going through the images, not the search links. The images got me to the pages I posted.

Hope it all works out!
