RPM/Tach/Shift light problems, help!

[Swifty1638]

all the fuses down by that panel look good. I can turn the key to on, and the light will flicker, but it won't turn on when it hit's the pre-set rpm (3k for now). I re-did the wire running to the pin 21 on the ecu, with a better connector, but still, nothing. power is still connected to that cigarette lighter wire (blue/white) and the ground is still off that bolt behind the driver's lower kick panel.
