hello,
i just replaced the ecu on my 420 rancher and the i can change gear at all,
all i get is 2 fast blinked 'N' which follow by 2 slow blinked 'N' (total of 4 blinks) and after the display stays on 'N' and no response from the gear.
does anyone have the error code list?
or even better anyone have any idea what can be the problem?

i double check the wires and tried all i can found online but still no help

thanks guys
