HI
I just fitted a set of Oxford Hot Grips. They are really easy to fit especially if you have one of Bigpies auxiliary fuse boxes.
Fitting is just a case of pushing them on, connecting the waterproof pugs and sockets, fitting the controller and linking to a power line operated through the ignition. They remember the last used setting, so just leave them switched on in the cold weather, mine are set to 20% as it was only 7deg outside this morning.
Regards
Graeme
