I am looking for coach wiring diagrams for a 1988 Superchief. I have not found a place to buy them. I am being this old motorhome back to life again but it's been hard to found parts. Thanks for any info Glenn
You might start with the diagrams for the 1990 SuperChief available here: Winnebago Wiring Diagrams. If you contact Winnebago directly they may have some available for your 1988 as well.
