Hi, there are two options...either find a used '74 TSM ( Technical Service Manual ) for an AMC, or find a Chilton's manual that covers the 70-74 Gremlins and Hornets. Either has a wiring diagram, but the Chilton's is small, and hard to read. I'm scanning it now, and sending parts of it to you. Maybe it'll help some. :) I've seen both the TSM's and old Chilton's listed at used book sites, the Gremlin Chilton's run about $6-12 each, plus shipping. The TSM's are about $35-40 plus shipping ( but those are year-specific, and MUCH better than the Chiltons ). Anyway, let me know if I can be of service to you in any other way...
