if it's 3 plugs, it's a OBD1 ECU/harness. check the OBD1 diagram here

ECU Pinouts, VTEC wiring, & ECU VTEC Conversion Information -

if your B10 is yellow/blue or orange color wire, then that's the one for your VSS

while you're at it, you can also check the ECU number and see which one your CRX is running to verify that it's a OBD1

if you're engine isn't original, check the engine model stamped on the block. here's a list of honda motors to triple check your OBD1
