I've got this complete - pick-ups, black box, and all the wiring but, but, but there are no instructions with it. It came off a failed 400 Four resto project I bought - allegedly running before it was stripped down, but then aren't they all?
I'll offer it here for £30 plus a fiver postage. It should fit any SOHC four. Money-back guarantee if it turns out to be a dud. Must be someone here who knows how to fit and set these things up. Otherwise it goes on eBay with a £49.95 start.
