Presumably they can supply the boots either end or do I have to canabilise the ones I have?
As a matter of interest can someone tell me whether they get a positive connection with the plug i.e. you can feel it snapping on to the plug when it's installed as I'm fairly sure this is where the problem lies - not so much with the wires themselves. It's almost as if the rubber collar is preventing the lead going far enough into the chamber?
Ta (again)
