This one has been used in an SR20 powered Datsun 1600. Its more of a starting point to construct one yourself, or you could go buy a brand new one from motec.
When I made mine up I used bits from a seconhand loom and got some new pins from Motec for the main ECU plug and made the rest up myself. Its not that hard if you can follow a wiring diagram and use a crimping tool.
