Hello! Brand new to the AMC scene. I just got an 87 Limited in remarkable shape (aside from 150k miles.) I live in New Mexico's Manzano Mountains outside of Albuquerque at 7300'. The car I bought is from PA and a low altitude car. A classified ad mentioned that the forums helped him out when changing low to high altitude. I've downloaded the "AMC Eagle Altitude Performance Adjustments" page and will do those mods, but I have 2 questions: Is the jumper wire (part # 318 6890) just a wire, or does it have a diode or similar device? TWO: the modification label # 8983 100 009 seems to be impossible to find. Can anyone with a high altitude modified wagon send me a pic so I might have it recreated? (4.2 automatic.) I'll post this in abbreviated form in another area if it seems appropriate. I should have the Eagle from PA shortly after the new year! CAN"T WAIT
