Can someone with wiring experience take a look and let me know if my assumptions are correct. Wiring is not my specialty to say the least.

Thank you in advance, Bob

No body has an oil pressure safety switch in there Pontiac?

looks like it will accomplish what you want, if you want to shut fuel off when there is no oil pressure, as long as the oil pressure builds enough to make the NO switch while cranking. to be clear the motor will run if they are full and then until the fuel bowls are empty wo oil pressure in this configuration. I believe it should, only one way to verify. I ran a similar set up on my nitrous fuel pressure to disable the nos solenoid if not enough fuel. It was finicky but the PSI threshold was much less then an oil pump obviously.

I have a Revolution Electronics fuel pump controller. It's been flawless for 58k miles.

Thank you for providing your input.
I added a momentary override switch in case the system needs to be primed.

That would work. lol... Thank you.

I believe you could also trigger the relay with the ignition terminal on your starter. Forgot what the terminal is labeled, but it’s the one that provides the points 12v while cranking.

[1] 30 amp relay would be more than adequate & easier/cheaper to find
[2] Both Holley & Carter make the three terminal, 1/8" NPT, switch you need.
[3] You will need ' Tee' fittings to integrate into the original oil pressure sw position...or....you could use the port next to the dist for the new switch.
