it's not quite as straighforward as using off the shelf parts without modification. In terms of steering controls, the interface is most similar to Honda Civics so that's the interface you start with, but the civic harness adaptor is not the same as the FRV. What you need to do is combine the 2... parts you need (pictured): Connects2 CTSHO001.2 Steering wheel control interface for Honda Civic Autoleads PC2-68-4 basic ISO harness CTMULTILEAD.2 steering wheel control patch lead (this one is universal but you can get specific ones for your brand of stereo, the instructions for teh universal patch shows you which wires to cut and which connector to use) CTSHO001.2 is the correct steering harness you need, but you need to chop off the Civic plug and replace it with the CRV/FRV one from a basic autoleads harness PC2-68-4. Your reference to the green plug, this doesn't fit anywhere on the harness, but these are for the steering controls. If you notice the grey plug in my picture with black and purple wires. This needs to connect to the green plug on the FRV wiring harness, except it won't fit. So you need to splice to black wire from grey plug on the interface to the orange wire on the green plug from the car. The remaining purple wire connects to the other wire (black/brown) Once everything is connected up, your controls should work.
