That's the same sensor I used. Just went to the local parts store and they had an adapter to make that work on my ls engine.

The engine was a 1991, no vortec, I couldn't find anyone that had anything that would work, picked up Autometer #2268 that is 16x1.5 with an 1/8NPT tapped hole figuring I could drill/tap it to fit the sensor if need be. I'm going to ask a dumb question (seems too easy so it'll probably never work) before I drill a hole in a $13 piece of brass, any reason you can't just tap the tan wire off the stock LS3 sensor to the tan wire going to the gauge and get it to work?

I just done that on a swap I done for a guy at work. We used the factory ls sensor in his truck and seems to be working just fine.
Awesome, I'm gonna try that first and hang on to the adapter if I need it. I figured it'd be too easy there would be no way it would work. Thanks for the info, I'll definitely follow up if it works.

Well the gauge is pegged all the way to the max and it does move some (but not much) when I turn it over but it doesn't reset back to 0, any ideas? Also, seems like the VATS wasn't turned off like it was supposed to be when I had the computer tuned because I tried to fire it and it starts, runs for a second and dies. But it did run so that's promising and with just headers it's loud as hell.

Just a follow up, I ended up picking up a brass adapter from the local parts store and drilling/tapping it for 1/2"NPT to get the 98 sensor to thread into the head on the engine, just connected the 1 tan wire to the gauge and it works like a champ. I just capped the orange and gray (?) wire coming off the pigtail and I'll just pull the wires going to the computer since the engine doesn't seem to care if it's not getting a signal.
