rb25det vct wiring

Recommended Posts

Only way to have a delay on the main pumps will be to drive them using a GP output and have a timer based delay triggered from the lift pump drive.

However it is more normal to activate all pumps off the one fuel pump drive at the same time.

The ECU only supplies the ground side, the +12V side comes from elsewhere in the car, most likely originally from the ignition switch or ECCS relay.  You will have to find a wiring diagram that matches your model if you want to troubleshoot the existing wire.

can i just run a wire from the alternator as it’s real close to vct plug or tap into the 12v cas wire which is also close
