It works now pal. What I did was put the oem connector in the ecu with the neccessary wire swapped out for the black box, so the steering wheel light came on the dash, but it didnt like it and shut off so I removed them all to not confuse the system and it sorted it.
And thanks I just realised it comes on without needing engine on. The adjuster seems kinda slow to change but it seems to work.
Big thanks for all your help as wouldnt of been able to do it without you. Also
@GrahamS helped me out lots too
Its too late now to go out for a test as getting in/out the garage is a skits mission so will drive out tomorrow. Will now clean up the wiring and tuck it back.
