B18FT ECU connections (migrating engine to another car)

[CraXyOW3]

I have been googling all information about this engine and the ecu, also searching these forums.
The B18ft engine was taken from a Renault 5 build, was not there for all connection when it was removed and now it is time for it to be put together again.

There are some splicing in the wiring loom 3 near the ecu and 4 a bit further away.

The one with 3 are:
Pin 5 Grounds injection ECU and screening cable for oxygen sensor (12)
Pin 9 Battery voltage controlled by the system relay
Pin 16 Receives a signal as soon as air conditioning is engaged in order to compensate for the additional load by adjusting the idle speed

The other 4 are:
Pin 1 Receives engine speed signal from ignition ECU (33)
Pin 14 Receives reference signal for CO–adjustment at idle from flow air mass flow meter (30)
Pin 16 Receives a signal as soon as air conditioning is engaged in order to compensate for the additional load by adjusting the idle speed
Pin 20 Receives a signal from the oxygen sensor

Also to note is that Ping 5 is grounded inside the connection in the wiring loom socket to the ecu.


Can not find a loose end to Pin 18 wich is 12v supply from ignition switch, should i splice this?

Thanks.
