those plugs dont get connected to anything. you take wires from the connectors to get the gauge cluster working.

ok ur gonna need a pin out from ur computer i have the pin out to a r33 rb20de and if it the same pinout i am more then happy to share it with youbut what ever you do DO NOT FOLLOW THOSES follow the COLOUR instuctions BECAUSE nissan never made a sertian colour for a certian application it really was whatever wire they had in the factory sometimes you'll get lucky but the more i work on nissan's the more i discover that

the ignition signal goes to the igtion switch, the wire that the click forward to start the car

ecu power and back up power if ur lazy u can wire rite up to ur battery but YOU HAVE TO! disconnect the battery everytime the car is off and ur computer will be reset evertime

there other things like the TACHOMETER signal that is wired stright to the ecu and water temp if u have more questions just ask i am open to help
