Hi , I have an overdrive kit to fit my R380 box and transfer , it comes ( as you know ) with a lever operation kit , that you fit and make I hole for it in the original soundproofing foam and use the rubber lever cover that it comes with to fit all three levers , has anyone ever fitted a solenoid to operate the overdrive via a switch rather than the lever , I am going to and wondered if anyone could recommend a solenoid to use ?
