Flex fuel sensors transmit two signals over one wire using a variable frequency and pulsewidth.  Only the DI's 1-8 can interpret this.  

If your car doesnt have cruise control then you could splice into one of the cruise DI's (DI6 or 7) or if you have cruise then the easiest option is probably DI8 (originally the start signal, which is not very important).

Thanks for your reply, 

also on CAN lamda,, is there any cam connection on main header for this or needs to go to expansion port ?

Says requires 1 digital input 

so can’t be on normal 0-5v analogue? 
 

Thanks Andrew
