Tach goes to tach signal behind teh gauge cluster and the a/f gauges goes to the o2 sensor wire at the computer. Dunno on a rb20 but on a rb25 which may or may not be the same the tach is pin 7 and the o2 is pin 29. Might be the same.

look on rb20det.com for the ecu pin out. it will tell you what wire is tach and 02 signal. If you bought one of those Autocrapper disco light a/f gauge save yourself some time and money and buy a good wideband setup. unless you just want that gauge for the flashing lights.
