I am on my third swap and I cannot for the life of me recall where I purchased the adapter so I can use the oil sender sensor from the motor in my dads 96 vortec V8 on the 4.8 that I am putting in... anyone ???
thanks in advance

Ebay or autometer makes one.
thanks for the reply.... looking for a part #,,,, ended up finding what I needed on ebay....
I've read tons of places that you can just wire in the LS pigtail and use the LS sensor for the Vortec 96+ OBS gauge since the LS PCM doesn't care about oil pressure. I wired in mine last night, so I guess I'm about to find out. lol.
The plugs were physically the same between the LS and Vortec pressure sensors on my engine. The difference being no back up fuel pump power on the LS. I do notice that the pressure reading on my dash runs between 40 PSI idle to 80 PSI WOT. That doesn't seem correct to me, and it's been that way between ls engines.
This is what I did on my swap.Quote:

Appreciate any info you can give me, also picked up the 3 wire coolant temp sensor and pigtail so gonna tackle that today.

Rock,,, you need this .. It will allow you to reuse the oil pressure sensor from your old motor.... swapping the 98 dash definitely add some complication to things...

Do you by any chance have the part number of the sensor you used? I've got BWD S4074 sensor and it's way bigger than 1/8 NPT thread. Appreciate the help, gotta get this thing running.Quote:

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.Quote:

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.
