      Terminator x max

      Regarding the oils pressure sensor on my ls3. The terminator harness plug for that sensor doesnt match.
      Can i just get the bare plug for my sensor and put it on the terminator harness without spending 137$ for the holley sensor?

      What is the sensor that comes with the LS3?

      I use ACDelco D1846A and it plugs right into the Holley harness. It does need a custom sensor configuration.

      If I can be of help with the tuning, please let me know.

      Holley sells the 558-416. It is a LS1 to LS3 MAP harness adapter.

      Let me know if I can be of service to help with wiring and tuning.

      If you got the wiring mojo to do that, then I highly recommend you do that. It is the best option. Be mindful of the pinouts between the ls1 and ls3 map sensors. They are not the same.

      Can a MAT sensor be installed where that port is coming out?
      It looks removable

      I generally recommend putting the MAT sensor into the intake tube, ahead of the throttle body.

      You can drill into the tube and tap it for 1/2" NPT. There is also an alternative sensor that slips into a rubber grommet, so you can make a hole in silicone elbow ahead of the TB.
