Does your tach have the ability to select between 4,6,8 and other signal? is it made to be wired to a coil signal or ecu?

did your stock tach work after you swapped in the RB? is your ground good?

Looks like you might need this adapter http://autometer.com/download_instruction/561.pdf

i bought it off some guy who also had an s13 rb20 and it work on his without the adaptor, btw i cant get ahold of the guy anymore this was awhile, anyway i tried the yellow/red wire coming from ecu pin#7 and the green one #5 and nothing. any ideas.

First thing you have to do is check if you are getting a signal from the tach wire from the ECU. If you have that, then obviously it has something to do with the tach or your wiring (power/ground/signal). I'm assuming the adapter is what autometer provides with their generic tach to serve all cylinder applications??
