Like the title says, these came with the 240sx when i bought it and i have no use for them…they are all electrical, do not include any extras, just the gauge with the wiring coming off the back so additional parts may be needed. to the best of my knowledge tho the a/f and voltmeter shouldnt need anything extra, not really sure on the oil pressure. will not seperate, someone just take all 3 for $35
