Injectors

i seem to remember that the diferent colors relate to different working presures so to be on the safe side id stick with the same that came out

thanks for the reply m8 i knew there was some reason you can't swap blue for brown would this be to do with the pulse voltage from ecu to injectors? reason for this question is i changed the whole loom and ecu form a 1994 car and put it on a 1997 car and noticed the injectors were brown on 1994 car and blue on the 1997 car and found fuel not geting to the spark plugs so long and short do i need the injectors (brown) to match the ecu am useing cheers rob

ok i found that yes the injectors have to match the ecu up and running now perfect cheers for help
