Oil Pressure sensor adapter for OBS swap

[1991SSP]

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

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.

This is what I'm stuck on right now with my swap, can you give me some details? To make things more complicated on myself I decided to swap a 1998 dash into my 1991 to go along with the LS3/TR6060 swap so I piicked up the sender and pigtail from a 1998 and was going to try to wire that in but the LS3 sender is bigger than the truck one so I started looking for an adapter, from what I found I believe I need a M16x1.5 to M12x1.5 but can't find one.

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.
