Thanks Dave, but like most old things, lacking detail. Anyone know which of the wires on the 1985 are Pickup Coil and Excitor Coil? The chart below, is what I've been able to compile from Wiring diagrams from 1985-2004. In case this doesnt come out, for 1985, what I am missing is the W/R; B/Y; R and B/R and which of these are assigned to Excitor and which are assigned to pickup?
