C34 injector relay location

[stove]

Hey guys, 

Just a quick one I can’t find any info on. Im installing a haltech elite 2000 into my c34 stagea. It requires a signal wire from the power output on the injector relay. I’ve tried the engine bay, under the drivers kick panel and drives coin tray but have had no luck finding the relay I need. If anyone knows of the injector relay location please let me know

It will be a blue relay above the ECU. If there are 2, one is the ignition and the other is ECCS (ECU power)

But what exactly is the input you need? Just ignition on (from the key) or something else?

^ This. There is not really an "injector relay". The ECCS relay powers up the ECU. It's not a simple thing though, because there are feedback loops and delays etc. You need to study the wiring diagram and use a multimeter to probe the various lines as you turn the key on, and off (and wait for 30 sec for the relay to time out!) and so on, to understand how it works.
