There are only 4 terminals. Brown-Acc, Red-Batt, Pink-Ign and Vio-Sol. As you can see on Funky61 switch, there is supposed to be another wire on the same terminal at the Pink Ignition wire. This is the resistance wire for the coil. I always just use a ballast resistor.

The radio picks up power from the 4A fuse on fuse panel marked "radio", should be BRN. Radio should have a ground wire or metal to metal.

Wire the 5 terminal just like the 4 terminal per above. The Ground terminal is not used on the fiver.
