If you can't get it online or e-mail from Crusader or dealer , I have the '88 Crusader Operations And Maintenance manual from my old engines. It covers all models & they all have the same Instrument Panel Wiring diagram on the last page. I do not have a working scanner and would rather not cut the pages from the manual (which I would like to keep), but could probably get the page flat-bed copied in town tomorrow and fax it to you later if you wish. Let me know if you need anything else from there, such as engine wiring diagram, general spec page, FWC or RWC system flow diagram, firing order diagram, maintenance chart.
