So if I've been trying to find all the ground locations on my 1984 grand Marquis. Does anyone have the diagram or map for this car. Been having issues with it dying on me while passing a few bumps. I was told that the ground braided wires go bad on these cars bt can't seem to find the locations for them other then the Negative ground cable on the battery

I got a 1984 Grand Marquis Ls and Everytime I got a bump or anything like that the car starts to sputter and then turns off. Bt starts right away. What could be causing that? Any suggestions?

I have a 1984 Mercury Grand Marquis Ls. I'm looking for parts at salvage or junkyard. Any recommendations
