If anyone has a FSM that would cover a 99 Sentra could you please tell me what are the colors of the wires from the ecu for:
Ignition Power, RPM, and Speedometer.

Thanks for anyones time for assisting me with this, I am just trying to hook up a Apexi Rev Speed Meter.
:confused:

here's what i can tell from the fsm

I think the rpm signal is L/OR which probably means light orange.

The speedometer signal comes from terminals 1 and 2 of the vehicle speed sensor. I think these are red and red/yellow.
do you want an ignition wire with power when the car is ON ar START? that should be yellow.

Good luck, I hope these are right.
