I just got my factory wiring schematics specific to the 86 ltd or marquis in the mail today. It's very detailed, more so than any others I have seen. If you need to see something, let me know and I'll try to get you some pics of the section(s) you need. About 30 pages of double sided diagrams that cover the different variations and models. Print is pretty damn small, but have circuit numbers and wire colors too. A lot of stuff I couldn't find anywhere online. If this is the wrong place for this thread, please move.
