I will refresh this a little bit.
I have v3.6 assembled ECU with PS2 connection. I ordered also wheelspeed cable. With cable there was small diagram.
Is connection to Dsub9 on this picture correct? (red colours)
1) I don't know what voltage my abs module is giving for the original ecu. It must be 0-5v. What if the voltage is higher that 5V. Does that cable will do the job and I don't have to worry about it?
2) +5V and GND on the wheelspeed Dsub9 should be connected to EC36pin28 and 26 (GND and +5V for sensors) ?
3) How to recognize that firmware is non-PS2 ? What firmware should I use for this cable?
Thanks.
