Did you install a 3 wire speed sensor in the W58?
What car do you have?
Are you using the factory dash for that car?
FYI the Jaycar kit does work with a 3 wire speed sensor, but not a 2 wire speed sensor
Also, have you tried without the Jaycar adjuster? The speedo should work, just not be accurate (perhaps your Jaycar adjuster ins't working?)...
Cheers
