vq climate control issues

[bike bling]

hi everyone I have a vq sv93 with climate control the problem being the relay for the compressor wont kick in it was regassed today with new sensors etc ive replaced the ecu and the control panel in the dash if I manually tigger the relay it comes on but dosent seem to be getting signal from the swith so im guessing that 86 on the relay isn't getting earth any other sugestions would be great also on a different post some said its a 5v trigger so the 12v relays wont work
cheers

Check that the low pressure switch is plugged in.
It should be on the passenger's side just next to the radiator.

Turned out to be a broken wire from front sensor
