define "gauge cluster does not work"

cuz if it doesn't work at all then he wired something wrong....probably not too hard of a fix. But if the gauges are just innaccurate then that's to be expected.

speedo signal from RB is KMH, vs MPH. So it should be off by close to a factor of 2. (mine reads almost exactly half of what it should). I think LS automotive makes a speedo that will work

as for tach....6 cyl output vs 4 cyl tach causes it to read 1.5x higher. CarlH on nico will modify ur DOHC tach to work perfectly with the RB signal for like $50. That's what i'm gonna do when i have more money.

hope that helps
