I recently purchased a 2018 Triumph Bonneville T120. I have the Dealer Tool which I have used on other bikes (Tiger 800 & Street Twin) and had no trouble connecting the diagnostic interface to them. The problem with the Bonnie is dis-connecting the attached leads. They seem to be secured differently than the other bikes. I am sure there is a simple tab or pull that I am not engaging but I am hesitant to pull too hard, lest I do something silly! If anyone would share with me the secret to undoing the lead so I could connect the Dealer Tool diagnostic interface I would be most appreciative.
