I’m finishing up the swap in my 70 Chevelle using Terminator X Max. I’ve got a Holley intake and fuel rail setup. My question is does anyone know what sensor will plug into the fuel pressure plug in the harness? I bought a ict adapter to screw in the fuel rail but can’t find a sensor that will plug up. Below is a picture of the plug on the Holley harness. My plan was to use the ICT adapter in the front of the driver side fuel rail and screw a sensor on the adapter. Any advice is appreciated.

The Holley sensors work very well and there are lower cost alternatives as well. Ideally the sender will be mounted away from the engine because the vibrations will kill the sensors prematurely, especially the lower cost ones.
If you need a hand with the tuning, please let me know.
I've used several different brands and have tested several of them and all of them have been with 0-3 psi of my air regulator I used as a reference, Even the Holley units read slightly different from one to the next.
Personal experience talking, spend the money on the holley fuel pressure sensor
What kind of issue did you have? I had two bad Holley sensors, One was dead out of the box but past warranty so they wouldn't help me, The other just quit working.
I had a cheap sensor on the car and it would only read 23psi fuel pressure. I’ve also had buddies kill low dollar Motorsports sensors but I believe their issue was the FPR and sensor were bolted to the motor and it vibrated them to death. My stuff is mounted on my brake booster and has been great
I have the LDM sensor and seems to be accurate but very little run time thus far. However my friend who’s been running his for awhile has had no issues which is why I went that route.
I would recommend mounting the sensor somewhere other than the motor. Also NHRA forbids the FPR to be mounted to the firewall in case the flexplate/flywheel comes apart if you plan on being competitive at a track
Made a bracket out of flat stock and bolted it to the brake booster for my FPR, no problems yet
My plan is to put mine directly on the fuel rail. Is it of the opinion that this will point will have too much vibration?
Keep it off the engine. The vibrations will kill even the good sensors eventually. I had a Holley sensor and it lasted 3 years on the engine. I bought a less expensive sensor and it literally lasted 2 minutes. I would also be very careful how you mount it on the rail. I nearly burned my GTO to the ground:
