no power; that was my thinking (because no box-armed LED activity). However I definitely tapped into the thick blue/yellow wire for power, so it ought to work? I blew my multimeter on something, so I cant really check outputs (have ordered a new one - fused!) but I noted some thick red wires tucked further up above the plugs behind the bonnet pull - ought I to try to tap into those? alternatively, perhaps I haven't grounded it correctly...I wired the black, yellow, and yellow/black wires to the chassis (crushed against the right angle bracket holding the bottom dashboard edge to the side of the car), assuming that to be an acceptable way to complete the circuit... Does that all sound reasonable? Thanks for the swift reply, joeadamou
