Oil pressure sensor option

While working out an oil pressure fitting adapter, I came across an OPS I had laying around. It has the right thread for an LS motor (M16), and it had the right connector from my old TBI harness. I figured I'd give it a shot and see how it read on the gauge. Turns out it read right about 60 psi on my dash cluster. Works great...

Now if I can only remember where I got it from. No part number that I saw on it, but it's GM. I must have snagged off a parts shelf years ago.

I'll be damned if I remember what it was from. If I figure it out though, I'll post the info up on here.

my tbi sensor was a 3 wire but different plug style than the 4.8 i got. and the 4.8 only had one out of the 3 terminals with a wire so I cut it and tied it into the center wire on the tbi connector and my oil pressure guage appears to operate just fine.
