EPS Wiring and control

I am retrofitting a classic car with the EPS steering rack out of a 2008 Civic Hybrid. I have all of the pieces I need to connect it up. I have the wiring diagram. I need three things to complete my project:

1. ECU pinouts.
2. DEP connection (Tach test signal) voltage level.
3. The signal type and levels on the CANbus speed signal.

If anyone has this information, I sure would appreciate getting it.

Also, does anyone know the module identifier?

Re: EPS Wiring and control

I have a schematic for the EPS system, but I presume it's for the Si trim and not the Hybrid.

Re: EPS Wiring and control

See the below links. First is a bit easier to read but doesn't include terminal numbers. The second, you will have to zoom way in to see anything.
