well i got this FCD from the previous owner, but it doesn't have the wiring harness that clips into the end of this unit but i figured i'd just cut the plug off and lengthen the wires a bit to reach the ecu. i'm gonna post a pic of it so you can see what im talking about but it's only 4 wires. i believe the red wire is ecu power, black is ECU ground, and the other two i dunno where they go, i think i read somewhere it goes to the ecu map boost sensor?
and the other to rev or speed limit sensor?
