I do have and original wiring [color=#282828][font=helvetica, arial, sans-serif]diagram in my files in attic thanks, the big prob with active circuit is that it is inside a square block which is filled with resin so there are no parts your can replace, would like something similar but using the same pickups if poss, there is only 2 wires coming from them so it would be ideal to get something that would fit into the same cavity as the Relfex system is a snug fit.[/font][/color]
