How can I tell if my Imperial is a Y Model? In the service manual I have #81-270-1001 on page # 2. The VIN. Code chart position #5 (car line) Imperial = Y . The wiring diagram for Y models page 8-398 (speed control) upper left hand corner indicates two fuse's #10 and #11. The fuse block in the car has a list of what the fuses protect on the cover under the dash. The list shows one fuse associated with the speed control. The wiring diagram shows two fuses #10 and #11. Am I looking at the correct wiring diagram? Lawrence R Noska lnoska@xxxxxxxxxxxx Hauser, ID 83854
