93 NA ATX 3000gt DOHC
I believe the second and third pictured connector halves are for oil pressure sensor and switch, that plug together (with blue end plastic on each) and attaches to far left plenum mount bracket. See below picture of far left connector B-06. The middle connector B-07 should be 4 wire connector, for rear back injector operation. Far right connector B-08 (already mounted in your picture) is 2 wire connector for knock sensor.The second one we have here runs across the plenum from the timing belt side to the throttle body side.
