Wiring diagram symbols

I recently purchased a 1994 Land Yacht, 30' motor home. It came with a complete owner's manual which I have read cover to cover. I am at a complete loss trying to figure out the symbols used on the wiring harness drawings.

Where can I get some help trying to figure out what these drawings are trying to tell me? I have tried for the last 2 hours searching the Air Forums site but with no luck.

Please help.

When I started to do my remodel I bought a couple of electrical books (12v & 112v) for RV's from Camper World and Vintage Trailer - great investment and will tell all.

Welcome to the AirForums!

Without knowing WHICH symbols you're trying to translate, my best suggestion would be to Google the phrase "electrical schematic symbols" and search in Images.

You're bound to find the specific symbols you're looking for.

I am familiar with normal electrical schematic symbols but the symbols used on the Air Stream wiring harness drawings do not resemble any schematic symbols I have ever seen. There are squares with circles inside and numbers in the circles. Sometimes the circles are diamonds or hexagons, again with numbers inside. There are circles with a square attached to one side and a line exiting the square which I assume is a wire. Inside the circle are some numbers, usually something like "1/4".

I was hoping someone had legend page that explained what the draftsman was trying to tell me. None of these drawings are numbered, only identified as "harness, body interior", etc.

I suppose that after I get a chance to tear into the wiring after I get it home and in my shop I will be better able to figure out what the symbols mean.
