Hello, all.
Just wondering if anyone out there has any good ideas about how to hook up an electric tach in a Spitfire that originally came with a mechanical drive tach.
I've got as far as understanding that one of the wires of three is ground, one needs to go to the negative side of the coil, but the other wire is a mystery to me. If you look in the Haynes wiring diagram it says that the third wire(going into the tach)is common to the brake light switch, and hazzards among other things and I don't know the easiest way of tapping in, and why I need to.
Has anyone else done this?
Thanks.
