You need to disconnect the harness and pull it through the intake.

Disconnect the O2 sensor, the switches on the tranny, the starter, oil pressure and knock sensor.

Make sure you remove the battery first.

Disconnecting the starter is the hardest part. after that is done everything else comes out in a couple minutes.

If you haven't changed your fuel filter lately, replace it now.

Take care.
