According to the wiring diagram :-

the wire you’re highlighting is black / white and should connect directly to earth.

Grn is earth and is gathered up and bolted to frame

Guys, I sent the ecu and ignition off, it came back but the bike will not start, fuel pump is not priming, spoke to person who did the programming and they have assured me the programming is fine.. the bike was fine up until removing ecu and ignition, has to be part of the hiss why it's not priming, maybe the antenna is not working all of a sudden, absolute gutted it didn't fire up after forking out all that money, is there any way I can narrow it down to it being hiss causing this problem, ie checking with multimeter? Also worth noting I have noticed on the instrument cluster there is usually a little led with a key icon I am sure that used to flash every so often, now it is just dead.

Definitely bad ECU/programming if that was only thing that changed.
Should get HISS light flashing when off for 24-hrs, then stops.
HISS light should go ON when key ON for 2-3s, then off and primes pump.
Did you fix that dodgy power wire? Measure it on ECU side when key ON/stop=RUN to make sure it has power. Also measure blk/wht at injectors and coils.

Thanks for your reply, I was almost convinced it was dodgy programming or ecu, big shout out to bikedecoders as they supported me thoroughly throughout my issue after doing a great job programming new keys at the best price and fastest turnaround, Lukas was sending me parts to fault find and trying to help, but.. in the end it was the bas sensor not supplying voltage to ecm .. another big shout out to Danny who posted this. https://cbrforum.com/forum/f4i-main-...1-06-a-163487/
This eventually led me to the problem, hope this post helps somebody one day, bikes in absolute bits and was just that ****ty sensor faulty, ah well.
Thanks for replys and support peoples. Don't lose your only key for any bike with hiss system.
