I'm going to use a 1G harness I have to cut out the plugs for the 1G cam sensor so I can rewire it into the 2G harness that way I don't have to use the 2G crank or cam sensor... I was going to use the 1G harness with a Galant VR4 ecu but the ecu doesn't have the Eprom chip plus nobody in Puerto Rico is programing them anymore so that's why I chose the 2G configuration so I can get the ecu re-flashed for my needs.
