i am looking for a little help. i picked up a knight sports ebs3 while i was in japan, the problem is that i got it from a junk yard and it was damaged so i got it really cheep. the cable going to the display was damaged, completely cut about 8 inches from the display. i repaired that so it is a bout 10 inches shorter now, but now i am left with a question as to which wires hook to what in the car. i can only guess that the red wire goes to a switched power, the orange wire goes to a constant power to keep settings, the light green wire goes to a dimmer, and the black wire goes to ground, but where do the rest of them go know at lease one goes to the BCS but that leaves two wires un-accounted for. any assistance would be greatly appreciated.

thank you in advance

there is only a green wire, and it goes to a dash light source. Other than that, it's simply a case of plugging the Knightsports harness in between the stock harness and the ECU. The sub-harness taps into constant power, switched power, and ground from the ECU to power the unit, so the additional wires are not for a power or ground connection. Are the extra wires spliced in, and if so where? Mine had two extra wires spliced in, and I suspect they were used to drive additional gauges (makes a good place to splice into the wiring harness without cutting the factory harness).

 

that would help out a lot if it still had the adapter harness that goes in between the factory wire harness and ecu but all i have are bare wires.

 

Wow, thats beyond me. could try contacting Knightsports I guess.
